The tetramethylbenzenes constitute a group of substances of aromatic hydrocarbons, which structure consists of a benzene ring with four methyl groups (–CH 3) as a substituent. [1] Through their different arrangement, they form three structural isomers with the molecular formula C 10 H 14. They also belong to the group of C 4-benzenes.
trans-3-Methyl-2-hexenoic acid (TMHA) is an unsaturated short-chain fatty acid that occurs in sweat secreted by the axillary apocrine glands of Caucasians and some Asians. [1] Hexanoic acids such as TMHA have a hircine odor. Of the fatty acids contributing to Caucasian men's underarm odor, TMHA has the most prominent odor. [2]
3,3-Dimethylhexane is a colourless, odourless liquid, chemical compound in the family of hydrocarbons which has a formula of C 8 H 18. It is an isomer of octane , where two methylene hydrogens at the third position in a hexane molecule have been replaced with two methyl groups.
2,3-Dimethylhexane Skeletal formula of 2,3-Dimethylhexane: Ball and stick model of 2,3-dimethylhexane: Names Preferred IUPAC name. 2,3-Dimethylhexane [1] Identifiers
Prehnitene or 1,2,3,4-tetramethylbenzene is an organic compound with the formula C 6 H 2 (CH 3) 4, classified as an aromatic hydrocarbon. It is a flammable colorless liquid which is nearly insoluble in water but soluble in organic solvents.
3-Hexyne is the organic compound with the formula C 2 H 5 CCC 2 H 5. This colorless liquid is one of three isomeric hexynes. 3-Hexyne forms with 5-decyne, 4-octyne, and 2-butyne a series of symmetric alkynes. It is a reagent in organometallic chemistry. [1] Structure of the coordination complex NbCl 3 (dimethoxyethane)(3-hexyne). [2]
It undergoes deprotonation at C-3 and C-1 with butyl lithium: HC 2 C 4 H 9 + 2 BuLi → LiC 2 CH(Li)C 3 H 7 + 2 BuH. This reaction allows alkylation at the 3-position. [2] Catechol borane adds to 1-hexyne to give the 1-hexenyl borane. [3] 1-Hexyne reacts with diethyl fumarate to produce n-hexylsuccinic acid. [4]
(CH 3) 3 C-CH=C(CH 3) 2 + CH 2 =CH 2 → (CH 3) 3 C-CH= CH 2 + (CH 3) 2 C= CH 2. It is a building block to synthetic musks by its reaction with p-cymene. It is also used in the industrial preparation of terbinafine. [1] In the study of C-H activation, neohexene is often used as a hydrogen acceptor. [2]
