Zeolitic imidazolate frameworks as heterogeneous catalysts for a one-pot P–C bond formation reaction via Knoevenagel condensation and phospha-Michael addition†
Abstract
A sequential one-pot reaction to produce organophosphorus compounds via Knoevenagel condensation and phospha-Michael addition has been realised by utilising ZIF-8 as a heterogeneous catalyst. The combination of 2-methylimidazolate anions and Zn2+ cations in ZIF-8 is revealed to be effective for the efficient promotion of the one-pot reaction.
