corresponding 2‐(trimethylsilyl)‐λ3‐phosphinine in good yields as a rather air and moisture stable, colorless oil. Insight into the regioselectivity of the pericyclic reaction was obtained with the help of deuterium‐labeling experiments. The silyl‐phosphinine acts as a ligand for the preparation of a Cu(I) and the first crystallographically characterized phosphinine‐Ag(I) complex. The title compound was further
2-吡喃酮和Me之间的[4 + 2]环加成反应3的Si-C≡P得到相应的2-(三甲基硅烷基)-λ 3 -phosphinine以良好的收率作为一个相当空气和湿气稳定的,无色油状物。借助氘标记实验,可以深入了解周环反应的区域选择性。甲硅烷基膦作为配体用于制备Cu(I)和第一个在晶体学上表征的膦-Ag(I)配合物。所述标题化合物还用作通过HCl的原去甲硅烷基化来替代制备母体膦的C 5 H 5 P的起始原料。C 5 H 5 P与CuBr⋅S(CH 3)2反应得到无限量的Cu(I)Br配位聚合物。DFT计算揭示了-Si(CH 3)3基团对芳族磷杂环的电子性质的影响。
