Abstract The P3-nortricyclane 4-methyl-1,2,6-triphosphatricyclo[2.2.1.02,6]heptane, CH3C(CH2P)3, (1), is synthesized in a better yield than earlier described from P4, a Na/K alloy, and CH3C(CH2Br)3 in boiling 1,2-dimethoxyethane. It reacts withM(CO)5 thf (M=Cr, W) in the molar ratios of 1:1, 1:2, and 1:3 to form the pentacarbonylmetal complexes CH3C(CH2P)3[M(CO)5] n [n=1, 2, 3;M=Cr (a), W (b)], (2 a, b–4 a, b).1 gives with Mo(CO)5 thf only mixtures of CH3C(CH2P)3[Mo(CO)5] n andcis-Mo(CO)4 derivatives, which were identified by their infrared active A1 v(CO) modes at 2075 and 2025 cm−1. All the new compounds have been characterized also by their1H{31P},31P{1H} NMR, IR,Raman, and mass spectra.
