Application of the donor-acceptor concept to intercept low oxidation state group 14 element hydrides using a Wittig reagent as a lewis base

This article outlines our attempts to stabilize the Group 14 element dihydrides, GeH2 and SnH2, using commonly employed phosphine and pyridine donors; in each case, elemental Ge and Sn extrusion was noted. However, when these phosphorus and nitrogen donors were replaced with the ylidic Wittig ligand Ph3P=CMe2, stable inorganic methylene complexes (EH2) were obtained, demonstrating the utility of this under-explored ligand class in advancing main group element coordination chemistry.

Organoboron Compounds, I. - Transformation of Phosphonium Ylides into Phosphane Monoalkylborane Complexes. - Hydroboration Reactions

Triphenylphosphonium ylides 1 add borane (from 2) with formation of alkylidenetriphenylphosphorane-boranes 3, which rearrange on heating to give the triphenylphosphane-monoalkylborane adducts 6.Compounds 6 can undergo hydroboration reactions.
