Aspects of the Chemistry of Donor Solvent Coal Dissolution Reactions. The Reduction of Benzophenone and the Diproportionation of Benzhydrol in Hydrocarbon Solvents at High Temperature
Choi, Chol-yoo,Stock, Leon M.

The reduction of benzophenone by hydrogen donor molecules such as tetralin and dihydroanthracene to give diphenylmethane was investigated in the temperature range 300-400 deg C.Several lines of evidence indicate that the reaction occurs in three distinct stages.The first stage is a radical process which gives benzhydrol.In the second stage, this intermediate undergoes an SN reaction to produce water and bis(diphenylmethyl) ether.The ether disproportionates in a readily initiated, free radical chain reaction to give diphenylmethane and benzophenone.

Simple and efficient methods were developed for sp2-sp3 and sp3-sp3 C-C bond-activation reactions of 2-substituted 1,3-diketones. 3-Substituted 3-bromopentane-2,4-diones were deacylated in the presence of an aromatic compound and a silica gel supported Bronsted acid containing sulfonic groups. The carbocation formed by cleavage of the sp3-sp3 C-C bond of the dione alkylated the aromatic compound.
INTERMOLECULAR CYCLIZATION OF o-FUCHSONES
Pisova, Milena,Soucek, Milan
, p. 838 - 842 (2007/10/02)
o-Fuchsones formed by dehydrohalogenation of o-hydroxyaryl(diaryl)methyl chlorides with tertiary amines undergo a cyclization to eight-membered dimers of the type head to tail.The dimerization reaction is catalyzed by tertiary amines hydrochlorides involving very likely triarylmethyl cation as intermediates.
