Abstract
Abstract [PdCl 2 (PPh 3 ) 2 ] suspended in MeOH reacts with carbon monoxide (40–80 atm, 50°C), in the presence of a base such as NEt 3 to give the methoxycarbonyl complex trans -[PdCl(COOMe)(PPh 3 ) 2 ]. When the carbonylation reaction is carried out at 90–100°C reduction to Pd 0 carbonyl-phosphine complexes occurs, with formation of dimethyl carbonate, selectively and in an almost quantitative yield. The above complexes are less reactive than the acetato-analogues, which give dimethyl oxalate as the main organic carbonylation product even at 50°C.
