Abstract
The hydrophosphination of heterocumulenes with Ph 2 PH using diethylzinc as precatalyst in neat conditions, which shows excellent catalytic effects. Intermediate is characterized to corroborate the proposed catalytic mechanism.
Commercially available compound ZnEt 2 acts as an efficient precatalyst for the solvent-free hydrophosphinations of heterocumulenes using Ph 2 PH as reagent. As far as we knew, this has been not reported in group 12 metal catalyzing reactions. A suggested mechanism of this reaction is explored, and the intermediate [{Ph 2 PC(N i Pr) 2 }ZnEt] 2 is obtained and characterized by a single-crystal X-ray structural analysis.
