Abstract: The unsymmetrical diborane(4) pinB–B((RN)<subscript>2</subscript>(C<subscript>6</subscript>H<subscript>4</subscript>)) (R = Me, Bn) reacts with [(Me<subscript>3</subscript>P)<subscript>4</subscript>Rh–X] (X = Me, OtBu) giving predominantly either [(Me<subscript>3</subscript>P)<subscript>4</subscript>Rh–Bpin] or [(Me<subscript>3</subscript>P)<subscript>3</subscript>Rh–B((RN)<subscript>2</subscript>(C<subscript>6</subscript>H<subscript>4</subscript>))] depending on X. At low temperatures in the presence of excess PMe<subscript>3</subscript> the unprecedented equatorial boryl complex [(Me<subscript>3</subscript>P)<subscript>4</subscript>Rh–B((MeN)<subscript>2</subscript>(C<subscript>6</subscript>H<subscript>4</subscript>))] is formed.
