Abstract
The diastereoselectivity of the rhodium catalysed hydroboration of div inylsilanes is found to vary according to the length of the tether bet ween the two phosphine ligands. Maximum diastereoselectivity is observ ed for butanodiphosphines and this may be related to the stability of a cis divinylsilane-diphosphine rhodium complex.
