DMT
Wed Mar 23, 2005 6:45 pm |

I remember a synthesis of DMT but I can't find it anymore anywhere.
It was posted by Rhodium and it wasn't about DMT (or 5-meo-DMT, i don't remember) but is was used as an example procedure.
I dont know what the starting precursor was but the procedure was that there was made an ester and from that ester was made the DMT. I dont know how. If it was a reduction or a breakdown. I dont know anymore but it produced DMT in high yield.
It also showed some schematics. The pics were placed under each shouder abd where the connections were made between the molecules were marked with big round mark. Like a bowling ball attached to a molecule.
Can anybody help me find it? |

I'm afraid that with such a vague description, you won't get much help...
(I don't know what you mean and really would like to look if I can find it; but searching for a synthesis of [either one or another] compound, starting with [unknown] reagents, involving an ester as intermediate and [reduction or breakdown] as technique to arrive at the final compound - there are too many synths out there that fit into this scheme, sorry)
maybe anyone knows what you mean by the description of the pictures that were included...
(good luck)

I have found it. What I meant was the Solid Phase DMT synthesis.
Thanks for retrieving all those hive files. |

Nice to hear you found it.
I'm looking for the hive thread number [523841], where psyloxy posted about the following article:
"Heterogeneous catalysts in the preparation of 2-aryl-1,3-dinitropropanes from beta-nitrostyrenes or benzaldehydes"
Angélica Fierro, Marcos Caroli Rezende, Silvia Sepúlveda-Boza, Miguel Reyes-Parada and Bruce K. Cassels
J. Chem. Research (S), 2001, 294–296
("http://12.162.180.114:90/synthetika/hiveboard/picproxie_docs/000523841-J_Chem_Res_Synop_2001_Nitrostyrene_preparation_reaction_with_excess_nitromethane.pdf")
The thread is here - I just need that article, if anyone has it please..

2,5-DMBA w/ nitromethane/Mn(OAc)2
Mon May 02, 2005 5:12 am |
|
|
Hi all, trying to find a post I remember, involved synthesis of 2,5-dimethoxybenzaldehyde from 1,4-dimethoxy benzene and nitromethane/Mn(OAc)2 . I remember there was only two posts in the thread - the reply was from Rhodium, but I cant remember who made the original post (it MAY have been psyloxy, but that's just a guess and could be wildly wrong!). I've done some pretty exhaustive searching, but it's eluding me completely!
Thanks in advance for any assistance provided! |

Ahhh, if only 'twere that simple... No, not what I'm after, I'm afraid. The reaction I want takes 1,4-dimethoxybenzene. That is reacted with Manganese (III) acetate (yes, I said Manganese (II) above, but brain is currently malfunctioning!) and nitromethane to give some sort of nitrate-like intermediate, which is in turn oxidised to 2,5-dimethoxybenzaldehyde (which would then be reacted with new nitromethane if one desired the nitrostyrene ). As I recall, the post may have been less than a year old, and, as I said, I think there was only the one reply to it from Rhodium (he gave two links to his page, one of which was a synthesis of Mn(OAc)3 .
Thanks for the effort anyway, though - appreciated  |

I am looking for Hive Post 468062 & Post 333934. SWIM needs to experiment with pseudo sulfate pills that contain Loratadine (Blue ones). I believe these posts will help. I have UTFSE, but find no good info.
Already looked at this post:
http://12.162.180.114:90/synthetika/hiveboard/crystal/000499993.html
Any help is appreciated. |

Hi would anyone know where I could lay my hands on this information?
"BzOH + HCl + H2O + calcium hypochlorite = benzaldehyde. Yields: 98%.
Post 513768 (Organikum: "Bleach + EtOH = Ethylacetate", Chemistry Discourse)
and
Post 513944 (Organikum: "From the "wanted references 1" ...", Chemistry Discourse)
the first reference here answers your question. "
Thanks |

P2P from aniline

Does anyone saved the thread about reacting diazotized aniline to P2P in one step? Lego was so stupid not to save her own posts
Thanks,

IMHO the nitrosophenol formylation looks better though. If someone has the belonging hive-post I'd be very glad.
Preparation of p-Nitrosophenol
In a porcelain glass equipped w/a stirrer, thermometer and a dripping funnel there's placed 45mls water, dissolved in it are 4.6g NaNO2 and 5g phenol melted in 15mls water are added thereto. Into the mixtr there's added 60g crushed ice and from a addition funnel there's added over an hour a cold soln of 2mls H2SO4 in 7mls water. The addition is done w/intensive stirring and good salt/icebath cooling – the temp should bee kept at 0 C. The rxn is stirred at this temp for further 2hrs, the product is filtered, washed w/cold water until neutral to litmus and dried at 50-60 C.
Yield 5.2g (80%)
(there's also a patent out there detailing how to get near quant. yields of pNP...)
Nitrosophenol formylation / HyperLab
In a 500mls 3-necked RBF w/a RC, 20g anisole and 30g wet NP is dissolved in 200mls EtOH. One neck is equipped w/a thermometer, the other one – w/a tube w/a porous glass filter. Thru it there's bubbled a gentle stream of HCl for 10-15mins. Then it is replaced w/a addition funnel, thru which 22mls of 40% formaline is added w/mag stirring so that the tem is kept in interval of about 50-55 C. After the addition is oer, the soln is boiled for 1-1,5 hrs. EtOH is removed in vacuo (to minimize hydrolysis of the methoxies), 100mls 12% NaOH is added and the aldehyde is xtracted w/ether; then purified or simply steam-distilled from the rxn mixtr (applicable to anisaldehyde and piperonal only).The yield – 13.3g (53% of theory)
IV. 2,5-diMeO-benzaldehyde. Obtained from 20g p-diMeO-benzene, yielding 13.5g (56%).

Lego - is this post of yours in the P2P compilation thread (which i happened to read yesterday)? this is not aniline itself so i'm not sure.
