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.

An efficient and novel Moβ zeolite catalyzed sp2-sp3 C–C bond development reaction over the direct coupling of alcohols and alkenes has been performed in solvent free environment. The current method gives an attractive access to a wide variety of polysubstituted alkenes in good to excellent yields. The Moβ zeolite was effectively reused for up to 5 successive cycles.

A new type of solid catalyst was prepared by coating a thin layer of policresulen, an inexpensive polymer prepared via condensation of 2-hydroxy-4-methylbenzenesulfonic acid and formaldehyde that has been used as commercially available drug, onto the surface of silica. The policresulen component is insoluble in many organic solvents and can be adsorbed on silica with the aid of hydrogen bonding. The obtained silica/policresulen composite showed remarkable catalytic activity for various organic reactions. In model reactions, the catalyst can be recycled several times without significant loss of activity. The salient features of using this acid catalyst in organic reactions include cost-effectiveness, simple and time-efficient preparation, and the convenience of controlling the acid loading on the solid.
Unusual reaction of allylic systems: homo- and cross-cyclizations leading to four-carbon rings
Siedlecka, Renata
experimental part, p. 2351 - 2355 (2009/07/18)
The reaction of stabilized allylic-type carbocations with electron rich olefins was investigated. In most cases a facile cyclobutane ring formation was observed by [2+2] cycloaddition reaction promoted by Br?nsted or Lewis acids. Some attempts were made t
