1,2,4-Trimethylbenzene, also known as pseudocumene, is an organic compound with the chemical formula C 6 H 3 (CH 3) 3. Classified as an aromatic hydrocarbon, it is a flammable colorless liquid with a strong odor. It is nearly insoluble in water but soluble in organic solvents. It occurs naturally in coal tar and petroleum (about 3%).
Compared to trimethylaluminium and trimethylgallium, InMe 3 is a weaker Lewis acid.It forms adducts with secondary amines and phosphines. [5] A complex with the heterocyclic triazine ligand (Pr i NCH 2) 3 forms a complex with 6-coordinate In, where the C-In-C angles are 114°-117° with three long bonds to the tridentate ligand with N-In-N angles of 48.6° and long In-N bonds of 278 pm.

Mesitylene or 1,3,5-trimethylbenzene is a derivative of benzene with three methyl substituents positioned symmetrically around the ring. The other two isomeric trimethylbenzenes are 1,2,4-trimethylbenzene (pseudocumene) and 1,2,3-trimethylbenzene (hemimellitene).
Trimethylgallium, often abbreviated to TMG or TMGa, is the organogallium compound with the formula Ga(CH 3) 3.It is a colorless, pyrophoric liquid. [1] Unlike trimethylaluminium, TMG adopts a monomeric structure. [2]
Trimethylamine (TMA) is an organic compound with the formula N(CH 3) 3.It is a trimethylated derivative of ammonia.TMA is widely used in industry. [5] [6] At higher concentrations it has an ammonia-like odor, and can cause necrosis of mucous membranes on contact. [7]
1,2,3-Trimethylbenzene is an organic compound with the chemical formula C 6 H 3 (CH 3) 3. Classified as an aromatic hydrocarbon, it is a flammable colorless liquid. It is nearly insoluble in water but soluble in organic solvents. The compound occurs naturally in coal tar and petroleum. It is one of the three isomers of trimethylbenzene.
Al 2 Me 6 + 3 H 2 O → Al 2 O 3 + 6 CH 4. Under controlled conditions, the reaction can be stopped to give methylaluminoxane: AlMe 3 + H 2 O → 1/n [AlMeO] n + 2 CH 4. Alcoholysis and aminolysis reactions proceed comparably. For example, dimethylamine gives the dialuminium diamide dimer: [7] 2 AlMe 3 + 2 HNMe 2 → [AlMe 2 NMe 2] 2 + 2 CH 4
