A novel diacylation of Schiff bases occurs in the presence of catalytic amts. of Co2(CO)8 under phase-transfer catalysis conditions. E.g., treatment of PhCH:NC6H4OMe-p with CO and MeI in CH2Cl2-H2O contg. polyethylene glycol and Co(CO)8 gives 68% MeCOCHPhNAcC6H4OMe-p and 11% PhCH2NAcC6H4OMe-p.

Abstract
A novel diacylation of Schiff bases occurs in the presence of catalytic amts. of Co2(CO)8 under phase-transfer catalysis conditions. E.g., treatment of PhCH:NC6H4OMe-p with CO and MeI in CH2Cl2-H2O contg. polyethylene glycol and Co(CO)8 gives 68% MeCOCHPhNAcC6H4OMe-p and 11% PhCH2NAcC6H4OMe-p.File in questo prodotto:
