Abstract

A Rh(I)Cl-DPPB-complex-catalyzed sequential hydroboration of aryl alkynes and aliphatic alkynes was achieved. The reaction proceeded with almost perfect regioselectivity to afford 1,1-organodiboronate compounds in moderate to good yield.

Key words

rhodium - hydroborations - alkynes - regioselectivity

<A NAME="RU00509ST-12">12</A> The regioselectivity was confirmed by ^¹H NMR, HMQC, and HMBC analyses. The crude products did not include 1,2-diboronate. The oxidation of product 2a under H₂O₂/NaOH conditions did not give 1-phenyl-1,2-ethanediol derived from 1,2-diboronate at all (unidentified products were obtained). The oxidation of 1,2-diboration product was reported, see: Trudeau S. Morgan JB. Shrestha M. Morken JP. J. Org. Chem. 2005, 70: 9538
