The meta and para OH substituted C-phenyl-nitrilimines were generated in argon matrices and characterized by IR spectroscopy and quantum mechanical calculations. Whereas the first exists as two bond-shift isomers of allenic and propargylic type, the second exists as single structure of significant allenic type. Results provided fundamental knowledge to understand the substitution effects on the structural nature of this important class of reactive compounds.

C-苯基-次氮基亚胺键移异构体的间位和对位羟基取代效应

间位和对位羟基取代的C-苯基-氮亚胺在氩气基质中生成，并通过红外光谱和量子力学计算进行表征。第一个以联二烯和炔丙基类型的两种键移异构体存在，而第二个以重要联二烯类型的单一结构存在。结果为理解取代对这一类重要反应性化合物结构性质的影响提供了基础知识。
