this heterogeneous rhodium complex is a highlyefficient catalyst for the hydrophosphinylation of terminalalkynes with diphenylphosphine oxide and can be recovered and recycled by a simple filtration of the reaction solution and used for at least 10 consecutive trials without any decreases in activity.Graphical AbstractHydrophosphinylation of terminalalkynes using diphosphino-functionalized MCM-41-immobilized
Various (E)‐alkenylphosphane oxides can be synthesized in a one‐pot manner under mild reaction conditions by using inexpensive Ceric(IV) ammoniumnitrate and without adding expensive metals and other additives.
