Abstract In an attempt to isolate new allylating reagents, two new tin compounds, triphenyl(1,2,3-trimethylallyl)tin ( 3 ) and triphenyl(1,1,2-trimethylallyl)tin ( 4 ) have been prepared and their crystal structures determined. Both compounds are examples of σ-bound allyl complexes. However, the infrared spectra of both compounds do not show the absorptions characteristic of other σ-bound allyl complexes
摘要为了分离出新的烯丙基化试剂,制备了两种新的锡化合物,三苯基(1,2,3-三甲基烯丙基)锡(3)和三苯基(1,1,2-三甲基烯丙基)锡(4),并且它们的晶体确定的结构。两种化合物都是σ-结合的烯丙基配合物的实例。但是,这两种化合物的红外光谱均未显示其他σ结合的烯丙基配合物的吸收特性。这些新化合物的化学性质也与相似的三苯基锡(烯丙基)试剂大不相同。
