Reductive Coupling between C-N and C-O Electrophiles

The cross-electrophile reaction is a promising strategy for C-C bond formation. Recent studies have focused mainly on reactions with organic halides. Here we report a coupling reaction between C-N and C-O electrophiles that demonstrates the possibility of constructing a C-C bond via C-N and C-O cleavage. Several reactions between benzyl/aryl ammonium salts and vinyl/aryl C-O electrophiles have been studied. Preliminary mechanistic studies revealed that the benzyl ammoniums were activated through a radical mechanism.

Preparation method of conjugated diene compound

The invention belongs to the field of fine chemicals and relevant chemical technologies and provides a preparation method of a butadiene derivative. The preparation method comprises the following steps of by taking phenylacetylene and a derivative thereof as raw materials, under the actions of a metal catalyst and an additive, performing reaction in an anhydrous organic solvent, and converting thephenylacetylene and the derivative thereof to a 2,3-di-substituted-1,3-butadiene compound. The preparation method has the beneficial effects of being simple and convenient to operate and mild in condition, being environmental friendly, having the possibility of realizing industrialization, and preparing the butadiene compound with a higher yield. The butadiene compound synthesized by utilizing the method can perform further functionalization to obtain various compounds, and then the compounds are applied to development and study of natural products, functional materials and the fine chemicals.

Solid Acid-Catalyzed Dehydration of Pinacol Derivatives in Ionic Liquid: Simple and Efficient Access to Branched 1,3-Dienes

The selective dehydration of pinacol derivatives to branched 1,3-dienes is extremely challenging because of the predominance of pinacol rearrangement. Herein, we successfully achieve this goal by employing a recyclable solid acid/ionic liquid catalyst system. The dehydration of alkyl- and cycloalkyl-derived diols in an Amberlyst-15/[Emim]Cl system afforded the corresponding 1,3-dienes in good yields, while a Nafion/[Emim]Cl system was demonstrated to be a better catalyst system for the dehydration of aryl-substituted substrates. Our protocol features straightforward and simple access to branched 1,3-dienes, high chemoselectivity, a recyclable catalyst system, a facile separation of dienes just by decantation, and a broad substrate scope.
