[(iminophosphine)nickel(allyl)]+ complex was found to be sufficiently electrophilic to activate aldehydes and N‐allylimines to undergo hydroboration with pinacolborane (HBpin) under mild reaction conditions. The catalyst displayed excellent selectivity toward aldehydes in the presence of ketones. A wide variety of functional groups were tolerated, including halogens, NO2, CN, OMe, and alkenes for both aldehydes
