Heterolytic H–H and H–B Bond Cleavage Reactions of {(IPr)Ni(μ-S)}2

Heterolytic H–H and H–B Bond Cleavage Reactions of {(IPr)Ni(μ-S)}2
Thomas R. Cundari, Frank Olechnowicz, Richard F. Jordan, Gregory L. Hillhouse
Kinetic and computational studies reveal that {(IPr)Ni(μ-S)}2 (1) reacts with H2 to produce {(IPr)Ni(μ-SH)}2 (2) via rate-limiting heterolytic addition of H2 across a Ni−S bond of intact 1, followed by isomerization at Ni and subsequent H migration from Ni to S. 1 reacts similarly with pinacolborane to produce {(IPr)Ni}2(μ-SH)(μ-SBPin) (3), showing that this reaction can be generalized to other H−E bonds.
