synthesised from (C6H5CN)2PdCl2 and (2-aminopyrimidinyl)phosphanes show different coordination modes depending on the nature of the amino substituent attached to the pyrimidine ring. Whereas P,N-coordination is observed for primary and secondary amino groups, tertiary amino groups lead to C–Hactivation at the pyrimidine ring. These differences result in strongly different catalytic activities in the
