The reaction of elemental white phosphorus with N‐alkyl acrylamides and N,N‐dialkyl acrylamides in the presence of a base is described and the physical properties of 8 new tertiary phosphine oxides of general formula (R 2 NCOCH 2 CH 2 ) 3 PO (R = H, CH 3 , C 2 H 5 ,(CH 2 ) 4 , (CH 2 ) 5 , and C 2 H 4 OC 2 H 4 , CH 2 CHCH 2 ) are reported. Interaction of white phosphorus with RNCS, RNCO, azo‐bis‐isobutyronitrile, Ph 2 NNPh 2 , vinyl acetate, vinyl ethyl ether, and expoxides has also been investigated.
