Reactions of Ph2PNRC(E)NRPPh2 proceed to give simple
P,P
chelate complexes when E=O but give the unexpected five-membered
true heterocycle Pt[Ph2PN(Me)C(NMeH)S]Cl2 and an unusual six-membered Pd2P2O2 ring when E=S. The X-ray structures of three examples are reported.
当 E=O 时,Ph2
PNRC(E)NRPPh2 的反应会产生简单的 P,P 螯合物,但当 E=S 时,会产生意想不到的五元真杂环 Pt[Ph2
PN(Me)C(NMeH)S]Cl2 和不寻常的六元 Pd2P2O2 环。本文报告了三个实例的 X 射线结构。
