A new polysiloxane-supported NAD(P)Hmodel, 1-benzyl-1,4-dihydronicotinamide, was designed and synthesized, which can efficiently reduce many activated olefins under mild conditions. The most advantageous features of this new polysiloxane-supported reductant are (i) easy workup and separation of the reaction products and (ii) good potential for recycling use of the reductant, which makes this new
and effectively catalyzes the Knoevenagel condensation reaction. After loading Pt nanoparticles onto this composite support, a tandem catalyst (Pt/CN‐ZrO2) is produced to be capable of the one‐step Knoevenagel condensation‐hydrogenation reaction to produce an alpha‐alkylated nitrile. The tandem catalyst exhibits >99 % aldehyde conversion and >99 % selectivity toward alpha‐alkylated nitrile under 1 MPa

PhosphoiminoBINOL-Pd2(OAc)2 complex catalyzed asymmetricMannichreaction of N-Boc imines with alkyl malononitriles, with assistance of Zn(OAc)2 gave chiral amines with adjacent all-carbon quaternary carbon centers in up to 99% yield with 94% ee.
Chiral Dinuclear Benzyliminobinaphthoxy‐Palladium Catalyst for Asymmetric Mannich Reaction of Aldimines and Isatin‐Derived Ketimines with Alkylmalononitriles
A newly developed dinuclear bis(benzylimino)binaphthol (BIB )−Pd complex showed good catalytic activity for the Mannichreaction of aldimines and isatin‐derived ketimines with alkylmalononitriles to give the products in a highlyenantioselective manner.
