Methylenetriphenylphosphorane is prepared from methyltriphenylphosphonium bromide by its deprotonation using a strong base like butyllithium: [1]. Ph 3 PCH 3 Br + BuLi → Ph 3 PCH 2 + LiBr + BuH
The reagent can be prepared in two steps from triphenylphosphine.The first step is P-alkylation with chloromethyl methyl ether.. PPh 3 + CH 3 OCH 2 Cl → [CH 3 OCH 2 PPh 3]Cl. In the second step, the resulting phosphonium salt is deprotonated.
Terphenyls are a group of closely related aromatic hydrocarbons.Also known as diphenylbenzenes or triphenyls, they consist of a central benzene ring substituted with two phenyl groups.
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.
Triphenylethylene (TPE) is a simple aromatic hydrocarbon that possesses weak estrogenic activity. [1] [2] Its estrogenic effects were discovered in 1937. [3]TPE was derived from structural modification of the more potent estrogen diethylstilbestrol, which is a member of the stilbestrol group of nonsteroidal estrogens.
