Abstract

Homoleptic lanthanide alkyls of the form Ln[CH(SiMe₃)₂]₃ (Ln = La, Nd, Sm, Y, Lu) and amides of the form Ln[N(SiMe₃)₂]₃ (Ln = La, Nd, Sm, Y) serve as efficient precatalysts for intramolecular homogeneous hydrophosphination. Both phosphinoalkynes and phosphinoalkenes undergo cyclization to the corresponding heterocyclic structures.
