Application of silica vanadic acid as a dual Lewis and Bronsted acid catalytic ability in Dakin West reaction
Silica Vanadic Acid, SVA, (oxo-vanadium has been supported on silica) as a dual Lewis and Bronsted acid ability was prepared and efficiently catalyzed one-pot multi-component condensation of enolizable ketones or alkyl acetoacetates with aromatic aldehydes, acetonitrile and acetyl chloride. The described reaction was produced β-acetamido ketone or ester derivatives in high to excellent yields i...
متن کاملPromoting the Hydrosilylation of Benzaldehyde by Using a Dicationic Antimony-Based Lewis Acid: Evidence for the Double Electrophilic Activation of the Carbonyl Substrate.
The concomitant activation of carbonyl substrates by two Lewis acids has been investigated by using [1,2-(Ph2 MeSb)2 C6 H4 ](2+) ([1](2+) ), an antimony-based bidentate Lewis acid obtained by methylation of the corresponding distibine. Unlike the simple stibonium cation [Ph3 MeSb](+) , dication [1](2+) efficiently catalyzes the hydrosilylation of benzaldehyde under mild conditions. The catalyti...

متن کاملAqueous Catalytic Polymerization of Olefins
Aqueous catalytic polymerization may seem like a contradiction at first sight. The high water sensitivity of Ziegler or Phillips catalysts applied commercially for the production of polyolefins is well known. However, water offers a unique combination of properties as a medium for polymerization reactions: A high heat capacity, which enables an effective transfer of the heat of polymerization. ...
متن کاملVersatile Catalytic Hydrogenation Using A Simple Tin(IV) Lewis Acid
Despite the rapid development of frustrated Lewis pair (FLP) chemistry over the last ten years, its application in catalytic hydrogenations remains dependent on a narrow family of structurally similar early main-group Lewis acids (LAs), inevitably placing limitations on reactivity, sensitivity and substrate scope. Herein we describe the FLP-mediated H2 activation and catalytic hydrogenation act...
