Abstract

PdCl2L2-type complexes with phosphines (L= PPh x (C6F5) 3-x (x= 0-3)), phosphites (L= P (OMe) 3, P (OPh) 3, P (OEt) 3), and phosphinites (L= PPh2 (OC6F5), PPh2 (O-3, 5-F2C6H3), PPh2 (OEt), PPh2 (On-Bu), PPh2 (Ot-Bu)) were synthesized and characterized by UV-vis and 31P NMR methods. PdCl2L2 complexes with less sterically demanding phosphines (Θ< 140°) exist as cis isomers, which is confirmed by the X-ray structure of cis-PdCl2 [PPh2 ( ...
