Reactions of catecholatoborane with phosphinorhodium complexes: molecular structures of [RhHCl(Bcat)(PPri3)2] and [{(Pri2PCH2)2}Rh{(η6-cat)Bcat}](cat = 1,2-O2C6H4)
Abstract
Addition of catecholatoborane (HBcat), 1, to [RhCl(N2)(PPri3)2] gives the first structurally characterised, unsaturated boryl complex, [RhHCl(Bcat)(PPri3)2], whereas reaction of [{(Pri2PCH2)2}Rh(η3-2-Me-allyl)] with 2 equiv. of 1 affords [{(Pri2PCH2)2Rh{(η6-cat)Bcat}]via B-substituent redistribution; both complexes catalyse the hydroboration of oct-1-ene with 1
