A catalyst-free method for the highly regioselective chloroboration of allenylsilanes is described. In the presence of BCl3 and 2,6-lutidine, chloroboration of allenylsilanes proceeds smoothly without any catalyst, and the product could be treated with pinacol to afford the corresponding pinacol borates in one-pot reaction. This reaction provides a direct approach to construct valuable 2-silylallylboronate frameworks with operational simplicity and high atom-economy.

A synthetic strategy for 'disarming' a terminal alkene by substitution with a bulky silyl blocking group has been developed. In a series of model studies, sequential selective ring-closing metathesis of trienes followed by selective mono-hydrogenation of the resulting diene is described. The bulky silylated alkene is activated for a subsequent cross-metathesis reaction with a range of diverse alkenes by protodesilylation.
