complexes, which are isolated in fair to good yields. This ring-opening and carbonylation reaction studied with a series of unsymmetrically substituted cyclopropenes, allows here the determination of the regioselectivity of opening depending on the nature of these substituents. The steric influence generally seems to be predominant, but electronic effects can also become very important in the case of π-donor

丙烯研究的这种开环和羰基化反应,可以根据这些取代基的性质确定开环的区域选择性。通常,空间影响似乎是主要的,但是在π供体取代基的情况下,电子效应也可能变得非常重要。
