A reductive reaction between titanates of α-keto aromatic acids and Li reagents

Abstract

Titanates of α-keto aromatic carboxylic acids ArCOCOOTi(OR^1)3 have been prepared to react with a series of Li reagents R^2Li and the ratioes of mole between reduction and addition have been investigated. The results indicate that the influence of R^2Li on the ratioes between the two reactions is quite weaker than that of OR^1. It is also concluded that the hydrogen which reduces the keto acids to mandelic acids comes only from α-carbons of R^1 or R^2.
