Cross ß-arylmethylation of alcohols catalysed by recyclable Ti-Pd alloys not requiring pre-activation.

Ti-Pd alloy catalysts were developed for the cross ß-arylmethylation between arylmethylalcohols and different primary alcohols via a hydrogen autotransfer mechanism. The alloy catalysts could be reused multiple times without the need for pre-activation. Analysis of the reaction solution by inductively coupled plasma atomic absorption spectroscopy indicated that only a minimal amount of Ti and no Pd was leached from the catalyst.
