Non-corrosive heteropolyacid-based recyclable ionic liquid catalyzed direct dehydrative coupling of alcohols with alcohols or alkenes

A non-corrosive, recyclable and efficient heterogeneous catalyst based on Keggin-type polyoxometalate, i.e., [NMPH]H3[SiW12O40] was developed for the direct dehydrative coupling of alcohols with alcohols (or alkenes) to synthesize various polysubstituted olefins in good to excellent yields. Furthermore, this reaction could be scaled up and the catalyst could be used for seven runs without significant loss of activity. The kinetic competition experiment shows that the C–H bond cleavage might be involved in the rate-determining step.

CaII-Catalyzed Alkenylation of Alcohols with Vinylboronic Acids

Direct alkenylation of a variety of alcohols with vinylboronic acids has been accomplished using the air-stable calcium(II) complex Ca(NTf2)2 under mild conditions with short reaction times. For reluctant transformations, an ammonium salt was used as an additive to circumvent the reactivity issue. Cross-coupling: Direct alkenylation of a variety of alcohols with vinylboronic acids has been accomplished using the air-stable calcium(II) complex Ca(NTf2)2 under mild conditions with short reaction times (see scheme)

Greener approach for the synthesis of substituted alkenes by direct coupling of alcohols with styrenes using recyclable Bronsted acidic [NMP] +HSO4- ionic liquid

A novel protocol for the synthesis of substituted alkenes from alcohols and styrenes using ionic liquid has been developed. The ionic liquid N-methyl-2-pyrrolidone hydrogen sulfate [NMP]+HSO4 - acts as a catalyst as well as solvent. The developed protocol has higher atom efficiency and wider substrate applicability. The catalyst was effectively recycled for up to five consecutive cycles. This journal is the Partner Organisations 2014.
