Boron bends over for nickel: The Ni complexes [tBu2PCCB(C6F5)2}Ni(cod)] (1) and [(tBu2PCCB(C6F5)2}Ni(NCMe))2] (2) derived from the reaction between the phosphino‐alkynyl‐borane tBu2PCCB(C6F5)2 and [Ni(cod)2] exhibit an unprecedented metal–alkyne interaction in which the borane substituent bends towards the metal affording a Ni→B dative interaction.
硼弯腰为镍:采用Ni配合物[吨卜2 PCCB(C 6 ˚F 5)2 }的Ni(COD)](1)和[(吨卜2 PCCB(C 6 ˚F 5)2 }的Ni(NCMe))2 ](2)从所述膦基炔基-硼烷之间的反应的吨卜2 PCCB(C 6 ˚F 5)2和[镍(COD)2]表现出前所未有的金属-炔相互作用,其中硼烷取代基向金属弯曲,从而提供Ni→B介导的相互作用。
