The reaction between F3PBH3 and CH3NH2 gives [CH3NH]F2PBH3, [CH3NH]2FPBH3, or [CH3NH]3PBH3 depending upon the experimental conditions used. In no case was CH3NH2BH3 ever detected as a product of the methylamine reaction. On the other hand the reaction between F3PBH3 and (CH3)2NH gave good yields of (CH3)2NHBH3 under conditions comparable to those used for methylamine, and gave [(CH3)2N]F2PBH3 or [(CH3)2N]2FPBH3 under more severe conditions. Displacement reactions provide a basis for listing the above bases in order of increasing base strength using BH3 as a reference acid. The order is: F3P < (CH3NH)F2P, [(CH3)2N]F2P < N(CH3)3, NH(CH3)2 < (CH3NH)2FP, [(CH3)2N]2FP. The results are discussed.
