Synthesis and Applications of Unquaternized C-Bound Boron Enolates

“…Catalyzed by copper hydride, , and with pinacolborane as the stoichiometric reductant, benzyl acrylate 1a was reduced as expected to O-boron enolate 2a . Upon the addition of a catalytic amount of phosphine or NHC, we discovered that an O-to-C isomerization occurred to generate a new species, C-boron enolate 3a (Scheme ).…”

Copper-driven formation of siloxanes via dehydrocoupling between hydrosilanes and silanols

“…Considering the precedent research by Schubert and Lorenz, 54 as well as our expertise in forging of Si-O bonds, we embarked on an investigation into the application of commercially available (triphenylphosphine)copper hydride hexamer, known as Stryker's reagent, [56][57][58][59] within the field of siloxane synthesis (Fig. 1c).…”

Trapping of soluble, KCl-stabilized Cu(i) hydrides with CO2 gives crystalline formates

“…An example is the hexameric hydride [CuH(PPh 3 )] 6 , 4 which has been introduced as a powerful tool in organic synthesis by Stryker. 5 The size of the Cu aggregates is determined by the sterics of the supporting ligands, and low-nuclearity hydrides have been reported for phosphine 6 and N-heterocyclic carbene complexes. 7 Cu( i ) hydrides accompanied by a BR 3 moiety are referred to as ‘masked cuprous hydrides’, of which complexes 1–3 in Chart 1 are examples (they may also be viewed as coordination compounds of HBR 3 − with Cu( i )).…”
