微波辐射下有机碲氧化物催化合成α,β-不饱和酮

THE USE OF MICROWAVE OVENS AND ORGANOTELLURIUM OXIDE FOR CATALYTIC RAPID SYNTHESIS OF α,β-UNSATURATED

以双-甲氧苯基氧化碲(BMPTO)作催化剂,在微波辐射下快速合成α,β-不饱和酮,产率达86%～95%.讨论了微波辐射功率、辐射时间以及不同催化剂对该反应的影响.实验表明,这一反应方法具有较强的实用性.

Some α,β-unsaturated ketons were prepared by the Claisen-Schmidt conden- sation reaction catalyzed by bis(p-methoxyphenyl)telluroxide(BMPTO)in the microwave ov- ens.This is a rapid organic synthetic method with the yields 86%～95%.All products are the E-isomers as confirrmed by their m.p.IR and ~1HNMR spectra.
