Novel and highly efficient one pot protocol for the synthesis of diversely functionalized triarylmethanes

An efficient, convenient, and novel one pot approach is described for the synthesis of triarylmethanes by in situ oxidation of benzylalcohols followed by the Friedel-Crafts alkylation of di/trimethoxybenzenes in the presence of BF3·OEt2. The generality of the present method is strengthened by screening a variety of aromatic, aliphatic, and heteroaromatic alcohols with methoxy arenes. Shorter reaction time, mild reaction condition, good yields, and wide scope of substrates are the significant features of this protocol.

Dimethoxy aromatic compounds VIII. Degenerate dealkylation-realkylation reaction of 1-bis(2,4-dimethoxyphenyl)-2-methylpropane

The condensation reaction under acid condition of the benzylic alcohols 1, 2 and 3 with the hexadeutero dimethoxybenzenes 4, 5 and 6 leads to the expected hexadeutero bis(dimethoxyphenyl)-2-methylpropanes 7, 8 and 9, respectively. However, the presence of both dodecadeutero and unlabelled 1- bis(2,4-dimethoxyphenyl)-2-methylpropanes 10 and 11 indicates that 9 undergoes a rapid degenerate dealkylation-alkylation reaction.
