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 novel, atom economical, and transition-metal-free strategy for the synthesis of thiophenes from substituted buta-1-enes with potassium sulfide has been presented. The reaction achieves double C-S bond formations via cleavage of multiple C-H bonds and provides an efficient approach to access various functionalized thiophenes. Moreover, the strategy can also be used for the synthesis of thiophenes from 1,4-diaryl-1,3-dienes. Mechanistically, DMSO plays a role of oxidant and S3?- in situ generated from K2S is involved.

Simple and efficient cross coupling of alcohols was developed in the presence of NaHSO4/SiO2 to give the corresponding substituted olefins. Direct coupling of alcohols and alkenes was also achieved to give substituted olefins. NaHSO4/SiO2 could be recycled 7 times without loss of catalytic activity.
