Sorry, Rhodium... I gotta quit reading your site after talking to that sweet cannabis sativa.
The link is on your page, Rhodium: https://www.thevespiary.org/rhodium/Rhodium/chemistry/methylenation.html (https://www.thevespiary.org/rhodium/Rhodium/chemistry/methylenation.html)
The procedure is the 4th one down (by Startinout).
I have a few more questions... I want to start experimenting with some of these procedures (all of them on that page, namely the 3rd and 4th one). Is there a way I can do inert gas shielding without fancy lab equipment? I have a lot of basic glassware, but I couldn't find any instructions on inert gas shielding.
I guess you do that in a glovebox?
Is the shielding to prevent side reactions? Is there a way I can hack around the inert gas shielding in the 3rd procedure? thanks for the help... peace
1) I don't think anything but pyridine hydrochloride would work as good in the microwave procedure, with the possible exception of triethylamine hydrochloride, but it will surely be lower yielding. I'd suggest that you use another method if you cannot get pyridine.
2 & 3) Did you read the whole document before asking? Check out https://www.thevespiary.org/rhodium/Rhodium/chemistry/methylenation.html#methylenation (https://www.thevespiary.org/rhodium/Rhodium/chemistry/methylenation.html#methylenation)
and you'll find a lot of different procedures for the methylenation step, many of which uses neither DMF or ether.
