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.
This compound is known as 2,3,3-trimethylpentane. Here three identical alkyl groups attached to carbon atoms 2, 3, and 3. Here three identical alkyl groups attached to carbon atoms 2, 3, and 3. The numbers are included in the name to avoid ambiguity about the position of the groups, and "tri" indicates that there are three identical methyl groups.
Like other hydroxylamines it will react with aldehydes to form nitrones, illustrative is the condensation with benzaldehyde to form diphenylnitrone, a well-known 1,3-dipolar compound: [4] C 6 H 5 NHOH + C 6 H 5 CHO → C 6 H 5 N(O)=CHC 6 H 5 + H 2 O. Phenylhydroxylamine is attacked by NO + sources to give cupferron: [5] C 6 H 5 NHOH + C 4 H 9 ...
Hagemann's ester, ethyl 2-methyl-4-oxo-2-cyclohexenecarboxylate, is an organic compound that was first prepared and described in 1893 by German chemist Carl Hagemann. The compound is used in organic chemistry as a reagent in the synthesis of many natural products including sterols , trisporic acids , and terpenoids .
The hexyl derivative is common test substrate because it is conveniently volatile. 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]
Triphenylmethanol features three phenyl (Ph) rings and an alcohol group bound to a central tetrahedral carbon atom. All three C–Ph bonds are typical of sp 3-sp 2 carbon-carbon bonds with lengths of approximately 1.47 Å, while the C–O bond length is approximately 1.42 Å.
