A novel diphosphino-functionalized MCM-41 anchored rhodium complex [MCM-41-2P-RhCl(PPh3)] was conveniently synthesized by the reaction of diphosphino-functionalized MCM-41 (MCM-41-2P) with RhCl(PPh3)3. It was found that this rhodium complex is an efficient catalyst for the hydrothiolation of terminal alkynes with thiols and can be recovered and recycled by a simple filtration of the reaction solution...
Diphosphino-functionalized MCM-41-immobilized rhodium complex (MCM-41-2P-RhCl3) was conveniently synthesized from commercially available and cheap γ-aminopropyltriethoxysilane via immobilization on mesoporous MCM-41, followed by reacting with diphenylphosphinomethanol and rhodium chloride. It was found that this heterogeneous rhodium complex is a highly efficient catalyst for the hydrophosphinylation...
