摘要

Ph_3PNCl(1) (1) originates in good yield as pale yellow crystals from the reaction of Ph_3PNSiMe_3 with phenyliodine dichloride. According to the crystal structure analysis 1 has a monomeric molecular structure without perceptible intermolecular contacts with distances P-N of 161.0 pm, N-Cl of 175.9 pm, and with a PNCl bond angle of 110.31 deg. 1 reacts with phosphines PR_3 forming asymmetric PNP salts [Ph_3RNPR_3]Cl. This was tested by reactions with PEt_3 and bis-diphenyl phosphano ferrocene (DPPF). The crystal structure analysis of [Ph_3PNPEt_3]Cl (2) shows an almost symmetric PNP bridge with distances PN of 158.6 and 157.0 pm, and with a bond angle of 145.9 deg.
