Abstract
In this paper, we highlight the synthesis of a variety of primary phosphine‐boranes (RPH2⋅BH3) from the corresponding dichlorophosphines, simply by using Li[BH4] as reductant and provider of the BH3 protecting group. The method offers facile access not only to alkyl‐ and arylphosphine‐boranes, but also to aminophosphine‐boranes (R2NPH2⋅BH3) that are convenient
