Abstract

Interaction of [Ph2PC (═ CH2) PPh2](A) 1–3 and/or [Ph2P (CH═ CH) PPh2](B) ligands in different molar ratio with hexacarbonyl metals M (CO) 6 gives [M (CO) n Ph2PC (═ CH2) PPh2] and/or [M (CO) n Ph2P (CH═ CH) PPh2 where M═ Cr, Mo or W, n= 2 and/or 4]. The carbon diphosphine complexes of type (A) which form four heteromemebered rings and/or type (B) form five heteromembered rings which reacts (addition reaction) with some ...
