An efficient and convenient uranyl-catalyzed reductive hydrosilylation reaction ofpara-quinone methides (p-QMs) was developed by employing silane as the reductant. The hydrosilylation procedure using the UO2(NO3)2·6H2

A mild and efficient method for the synthesis of unsymmetrical diaryl- and triarylmethanes through a B(C6F5)3 catalyzed reduction of para-quinone methides and fuchsones respectively, using the Hantzsch ester as a reducing source has been developed. Detailed mechanistic investigations revealed that the reaction actually proceeds through a Lewis acid-base pair complex derived from B(C6F5)3 and the Hantzsch ester.

An iridium-catalyzed hydrogen-borrowing process has been developed whereby 2,6-di-tert-butylphenol can be alkylated at the C4-position by using a range of primary alcohols (11 examples, 40-93% yield). Following this, a selection of the products obtained underwent retro-Friedel-Crafts reactions to provide para-substituted phenols, which could potentially undergo further synthetic manipulations.
