DL-Alanine can make nitroethane
4-bromo-3-methylphenol - Could easily make DOM
4-bromophenol - Methylate the hydroxyl, then hydroxylate the bromo, p-methoxy phenol--great 2CB percursor
1-bromopropane - Maybe propionic acid. Probably not.
o-anisealdehyde - You can oxidize the aldehyde to a hydroxyl with H2O2+H2SO4, thence to 2CB
4-bromo-N,N-dimethylaniline - Maybe a Grignard to make DMT? Seems far-fetched.
2-bromo-2-methylbutane - Probably not
tert-butyldimethylsilyl - Probably not
benzyl alcohol - You could either halogenate the hydroxyl, to make Benzyl chloride--a meth precursor, or oxidize to make benzaldehyde--another meth precursor
2-benzylpyridine - Maybe useful as a pyridine substitute. Nothing springs to mind
4-bromobenzaldehyde - Probably not.
benzophenone - Dunno
p-cresol - I know this can be used as a mescaline precursor.
crotyl chrloride - dunno
L-cysteine - No
carbon tetrabromide - Dangerous, but probably a useful solvent
3-cyanobenzaldehyde - dunno
4-chlorobenzaldehyde - dunno--note that 4-chloroamphetamine is neurotoxic
4-(dimethylamino)pyridine - again a possible pyridine subst.
1,3-dicyclohexylcarbodrimide - dunno
2,2-dimethoxypropane - Dunno
diethanolamine - You can make morpholine out of this, and then use that as a catalyst in a Willdergodt reaction
diphenylmethane - I doubt it
3,4-dimethoxyphenol - YES!!!!! This is a fantastic TMA-2 precursor. You should be able to formylate using a variety of methods, then methylate, and condense with nitroethane. Reduction yields TMA-2
2,6-dimethoxybenzaldehyde - This should be usable for a number of Shulgin's 2,6 subst. phenethylamines, eg. TMA-6.
ethyl 3-coumarin-carboxylate - Probably not.
flourene - Very dangerous to handle. Probably not that useful anyway.
bromine - Useful for a variety of things.
4-hydroxycinnamic acid - Maybe you could make mescaline out of this.
glutaric anhydride -
hydrocinnamaldehyde -
4-hydroxybenzldehyde - Definite mescaline or escaline precursor
hydrazine - I understand this is used in LSD production. It is also useful in some reductions.
3-(4-hydroxyphenyl)-1-propanol - Yes. You should be able to dehydrate that propanol chain, then methylenate the ring to yield isosafrole, an MDMA precursor.
N-hydroxysuccinimide - If you could halogenate that hydroxy group with something like PBr3 or PI3, you could make N-halo-succinimide--a useful halogenation reagent.
DL-Lysine - Probably not.
2-methyl-2-propanol - Probably not
methyl-d3-amine HCl - No, unless you want to do radiotagging studies with MDMA or meth.
4-nitrobenzaldehyde - dunno
m-nitroaniline - dunno
1-naphthol - Probably not
4-nitrophenol - dunno
4-nitrobenzyl chloride - dunno, probably not
4-nitrophenyl chloroformate - dunno
3-nitrobenzaldehyde - dunno
o-nitrophenol - dunno
4-nitrobenzyl bromide - dunno
4-nitrobenzaldehyde - dunno
nitromethane - Yes, you can condense this with aldehydes to form nitrostyrenes, which can then be reduced to phenethylamines.
trans-stillbene - dunno
p-toluenesulfonic acid monohydrate - Useful as a catalyst in a number of things
triphenyl methane - Maybe.
L-tyrosine - It'd be difficult to use.
p-toluoyl chloride - Dunno.
2,4,6-trimethylphenol - Dunno.
iodine - Yes.
LiAH - yes.
Aluminum Chloride - yes
Barium Hydroxide -probably
MgCl - probably, though I think you have a typo in the name.
Mercury(II) acetate - Likely yes
acetic anhydride - Definitely useful for preparing ketones from phenylacetic acids.
I strongly advise you learn something about organic chemistry before trying anything with any of these. Some of the chemicals can be very dangerous.
