The present invention relates to a versatile, highly efficient process for the preparation of mono- and bisacylphosphanes as well as for their corresponding oxides or sulfides. The invention further relates to novel photoinitiators obtainable by said process.
A new synthesis of bis(acyl)phosphane oxide (BAPO) photoinitiators was developed which can be used to functionalize cellulose nanocrystals surfaces for polymer grafting. Hybrid materials with excellent graft yields can be...
