Abstract
Abstract The reaction of 1-methyl-2-chloro-3-dichlorophosphinyl-1,3,2λ3-diazaphosphorinane 1 with (norbornadiene)tetracarbonylmolybdenum(0) in a 2:1 molar ratio furnished cis-bis(1-methyl-2-chloro-3-dichlo-rophosphinyl-1,3,2-diazaphosphorinane)tetracarbonylmolybdenum(0) 2. In 2, one ligand 1 is bonded to Mo(0) via the Pcl group, the other through the Pl2 group. 1-Methyl-2-methoxy-3-dimethoxyphos-phinyl-1,3,2λ3-diazaphosphorinane 3 reacted with norbornadienetetracarbonyl-molybdenum(0) to form the chelate complex cis-(1-methyl-2-methoxy-3-dimethoxyphosphinyl-1,3,2-diazaphosphorinane)tetracarbonylmolybdenum(0) 4, in which one molecule of the ligand 3 is attached to Mo(0) in a chelating fashion, coordinating through both the POCH3 and the P(OCH3)2 group. In the reaction of 3 with (COD)PtCl2 (COD = 1,5-cyclooctadiene) in a 2:1 molar ratio the ionic bis-chelate complex cis-bis(1-methyl-2-methoxy-3-dimethoxyphosphinyl-1,3,2-diazaphosphorinane)-platinum(II)chloride 5 was formed. Two molecules of 3 are coordinated...
