The chlorotriborane(7) (B3H6Cl) adduct of N(CH3)3 was formed by the reaction of B4H8·N(CH3)3 with HCl in dichloromethane or with HgCl2 in chloroform. The reaction of B3H7·N(CH3)3 with BCl3 in dichloromethane was found to be a better preparative method for B3H6Cl·N(CH3)3. The BCl3 treatment was employed to convert the N(CH3)2H, N(CH3)H2, NH3, and S(CH3)2 adducts of B3H7 into the corresponding adducts of B3H6Cl. In contrast, B3H7·P(CH3)3 and B3H7·PH3 are inert to BCl3. The B3H6Cl adducts of P(CH3)3 and PH3 could be obtained by treating the B3H7 adducts with a mixture of HCl and BCl3 in dichloromethane. The 11B and 1H NMR spectra of these B3H6Cl adducts showed that their structures were described as 1-(Lewis base)-2-chlorotriborane(7).
