A B(11) NMR Study of the Closo-hydridorhodacarborane 3,3-((C2H5)3P)2-3-H-3,1,2-RhC2B9H11(Ia) Prepared in situ from 3,3-(Ph3P)2-3-H-3,1,2-RhC2B9H11(i).

Abstract

A complete assignment of the B(11) NMR spectrum (111.8 MHz) of 3,3-(C2H5)3P)2-3-H-3,1,2-RhC2B9H11(Ia) is proposed on te basis of B(11) NMR data obtained from specifically deuterated derivatives of I, and from 3,3-(Ph3P)2-3-H-9,12-(Br)2-3,1,2-RhC2B9H 9 and 6-Ph-3,3-(Ph3P)2-3-H-3,1,2-RhC2B9H10. The B(11) NMR Of compound 1a above in tetrahydrofuran consists of five resonances of relative intensity 1:1:2:2:3 (reading upfield) which are assigned to B(10), B(8), B(9,12), B(4,7),B(6) and B(5,11), respectively.
