The Peterson olefination for alkylidenecycloproparene synthesis from a 1,1-disilylcycloproparene has been refined into five distinct protocols that have provided 43 new aryl- (5 and 6) and diaryl- (7 and 8), and aryl(phenyl)- (9 and 10) methylidene derivatives. The permanent dipole moments of these and other previously reported compounds have been measured and the direction of the dipole, to or from
由1,1-二甲硅烷基环丙烷合成亚烷基环丙烷的彼得森烯化反应已被精制为五种不同的方案,提供了43种新的芳基-(5和6)和二芳基-(7和8)以及芳基(苯基)-(9和8)。 10)亚甲基衍生物。已经测量了这些化合物和其他先前报道的化合物的永久偶极矩,并确定了每种化合物的偶极方向,即去往或来自环丙烯基的部分。完全分配了13C NMR光谱,并为包含在5-10中存在的每个取代模式的8-11化合物提供了碳化学位移与环丙烯部分中每个原子的Hammett sigmap +常数的线性相关性。
