| Popis: | Transvinylation of aromatic and aliphatic diacids w ith vinyl acetate using several catalytic systems have been studied under conventional heatin g and microwave activation. In any case, a single addition of catalyst gave only low conversio n into diester, due to a rapid deactivation of the catalysts, the best results being obtained with [pyridine] 2·Pd(OAc) 2. Successive additions of Pd(OAc) 2 as catalyst gave better results with a 65% yield in is olated pure divinyl dodecanedioate after the successive addition of three catalyst por tions. Kinetics and catalytic mechanism considerations helped to discuss these results. |
