The trimethylbenzenes constitute a group of substances of aromatic hydrocarbons, which structure consists of a benzene ring with three methyl groups (–CH 3) as a substituent. [1] [2] Through their different arrangement, they form three structural isomers with the molecular formula C 9 H 12. They also belong to the group of C 3-benzenes.
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).
(Mesitylene)molybdenum tricarbonyl arises from the reaction of molybdenum hexacarbonyl with hot mesitylene: [1]. Mo(CO) 6 + (CH 3) 3 C 6 H 3 → Mo(CO) 3 [(CH 3) 3 C 6 H 3] + 3 CO It can also be synthesized, with good yields by displacement of pyridine ligands of the trispyridine complex Mo(CO) 3 (pyridine) 3 in the presence of Lewis acids.
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%).
