Abstract

Hydroboration of the electron poor phosphine (1-propenyl)P(C₆F₅)₂ with Piers' borane [HB(C₆F₅)₂] gave the geminal frustrated Lewis pair (C₆F₅)₂P–CH(Et)–B(C₆F₅)₂. It undergoes 1,2-addition reactions to an alkene and an alkyne and to the C [double bond, length as m-dash] N bond of an isocyanate. With mesityl azide it undergoes a 1,3-addition reaction.
