Reactions of alkene or alkyne with diphenylphosphine and catalytic [κ5‐N,N,N,N,C‐(Me3SiNCH2CH2)2NCH2CH2NSiMe2CH2]Zr (1) are greatly enhanced under photolysis, providing viable catalytic hydrophosphination with a broad substrate scope. Whereas diphenylphosphine had been an inaccessible substrate under thermal conditions, complete conversion of alkene substrates to tertiary phosphine is achieved in as
与二苯膦和催化烯烃或炔烃的反应[κ 5 - Ñ,Ñ,Ñ,N,C - (ME 3 SiNCH 2 CH 2)2 NCH 2 CH 2 NSiMe 2 CH 2 ]锆(1)都大大下光解增强,提供了广泛的底物范围可行的催化加氢磷酸化。而二苯基膦已经热条件下无法访问的基板,烯烃底物的叔膦的完全转化在少在与环境温度下实现的四个小时1在紫外线照射下。以前的惰性烯烃现在是具有二苯膦的加氢磷酸化底物,以产生具有可调的空间和电子特性的叔膦配体。
