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.
The Ph 3 C-H bond is relatively weak, with a bond dissociation energy (BDE) of 81 kcal/mol, or about 24 kcal/mol less than methane. [4] Correspondingly, triphenylmethane is mildly acidic, with a pK a of 33.297.
Prehnitene is one of three isomers of tetramethylbenzene, the other two being isodurene (1,2,3,5-tetramethylbenzene) and durene (1,2,4,5-tetramethylbenzene). [1] It is a relatively easily oxidized benzene derivative, with E 1/2 of 2.0 V vs NHE.
With respect to donor properties, dimethyl sulfide is a soft ligand with donor properties weaker than phosphine ligands. [3] Such complexes are generally prepared by treating the metal halide with the thioether. Chloro(dimethyl sulfide)gold(I) can however be prepared by redox reaction of elemental gold and DMSO in the presence of hydrochloric ...
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.
In organic chemistry, hexene is a hydrocarbon with the chemical formula C 6 H 12. The prefix "hex" is derived from the fact that there are 6 carbon atoms in the molecule, while the " -ene " suffix denotes that there is an alkene present—two carbon atoms are connected via a double bond .
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-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]
