The past 5 years has witnessed considerable growth in the field of borocation chemistry with a multitude of new cations containing 2, 3 and 4 coordinate boron centres reported. Perhaps more significant has been the expansion in the synthetic utility of borocations as stoichiometric reagents and catalysts. It is these new applications of borocations that are the primary focus of this article which concentrates on reports from 2009 to the end of June 2014. The correlation between structure and reactivity in these recent studies will be emphasised to aid in the future design of new borocations for specific targeted outcomes.
