Abstract:Phosphagermylenylidenes
(R–PGe), as heavier analogs
of isonitriles, whether in their free state or as complexes with a
Lewis base, have not been previously identified as isolable entities.
In this study, we report the synthesis of a stable monomeric phosphagermylenylidene
within the coordination sphere of a Lewis base under ambient conditions.
This species was synthesized by Lewis base-induced dedimerization
of a cyclic phosphagermylenylidene dimer or via Me3SiCl
elimination from a phosphinochlorogermylene fr… Show more
