Product: (Trimethylsilyl)acetylene CAS: 1066-54-2 Purity:97% Commodity Code:2931900090 MDL Number:MFCD00008569 Synonyms:Ethynyltrimethylsilane 4,6,8-Trimethyl-, 1,4,6,8-tetramethyl-, 2,4,6,8-tetramethyl-, 4,6-diphenyl-8-methyl-, and 3,8-dimethyl-7-isopropylazulene have been acylated with trifluoro- and trichloroacetic anhydrides. Mortality: No deaths occurred following a 4-h exposure to 2000 ppm TMA; 3 of 6 rats exposed to 3500 ppm died during the exposure period Clinical signs: other: During exposure, all rats showed labored breathing, nasal and oral discharges, and neither moved nor responded to sound. Rats exposed to 3500 ppm also had dry red nasal and ocular discharge during the early stages of the postexposure period. Radical Arylation Reactions of 4, 6, 8‐Trimethylazulene.

2012-12-18 · Trimethylaluminum (TMA) complexes of methyl-, n-propyl-, cyclopropyl-, allyl-, and propargylamine were synthesized and their experimental properties and theoretical characteristics were compared with the respective amine–borane analogues. The amine ligand of an amine–TMA Lewis acid–base complex can be easily changed by another amine through a 2:1 amine–TMA intermediate in pentane at

This causes the separation of a dark violet oil which is taken up in Trimethylamine (TMA) is an organic compound with the formula N(CH 3) 3.It is a colorless, hygroscopic, and flammable tertiary amine.It is a gas at room temperature but is usually sold as a 40% solution in water.

In investigating and seeking to mimic the reactivity of trimethylaluminium (TMA) with synthetic, ester‐based lubricating oils, the reaction of methyl propionate 1 was explored with 1, 2 and 3 equivalents of the organoaluminium reagent.
