Abstract

Novel triphenyl phosphine ligands bearing pyrazole or 2-aminopyrimidine groups in the ortho or meta position of one or three of the phenyl rings were obtained starting from the corresponding acyl derivatives Ph2P (o-C6H4-COCH3), Ph2P (m-C6H4-COCH3), or P (m- C6H4-COCH3) 3. Conversion of the acyl groups into 3-dimethylamino-2-propen-1-onyl units was achieved by reaction with HC (OMe) 2NMe2 which underwent ring closing with ...
