The reversed regiochem. of the Rh-catalyzed hydroboration of styrenes by catecholborane could be further reinforced by the addition of some metal halides, Lewis acids and mol. sieves. E.g., hydroboration of styrene with catecholborane in the presence of Wilkinson catalyst and ZnCl2 gave, after treatment with aqueous H2O2 and NaOH, 95% alcs. I and II (I/II = 98/2).
