The rhodium-catalyzedaddition reactions of trimethyl(phenyl)stannane and sodium tetraphenylborate to N-phenylsulfonyl aldimines RCHNSO2Ph (R=alkyl and aryl) provided R(Ph)CHNHSO2Ph in high yields. A cationic and free phosphine complex [Rh(cod)(MeCN)2]BF4 was found to be an efficient catalyst for the addition of PhSnMe3, whereas [Rh(cod)(MeCN)2]BF4/dppb catalyzed the addition of Ph4BNa to various

The hydroxylation of organometallicreagents (RM) by 2-sulfonyloxaziridines 1 is shown to involve a hemiaminal intermediate 2, whose stability is apparently related to the nucleophilicity of the hydroxylated product (ROH).
