From a Phosphagermaallene −P═C═Ge< and Heavier Chalcogens (S, Se, Te): Access to 3-Phosphanylidene-1,2-Chalcogenagermiranes
摘要:
Chalcogenagermiranes that feature an exocyclic P=C double bond were obtained from the phosphagermallene Mes*P= C=Ge(t-Bu)Tip (Mes* = 2,4,6-tritert-butylphenyl, Tip = 2,4,6-triisopropylphenyl) and heavier chalcogens. The structural data of selena- and telluragermiranes show they are intermediate between a normal three-membered ring and a pi-complex.
