A simple and operationally easy protocol for the regioselective synthesis of internal alkenes through a dehydrative cross-coupling and direct coupling procedure has been described using the environmentally benign Ca(II) catalyst. Several alkenes and alcohols underwent the coupling reaction under solvent-free conditions in a short time to produce the desired alkenes. This method is further extended to show the application in the synthesis of novel benzopyran molecules through a cascade strategy.

The reaction of styrene with α-methylstyrene has been studied over Y, Beta and ZSM-12 zeolites at 80-120 °C in the presence or absence of chlorobenzene. Homo- and codimers of styrene and α-methylstyrene were the main reaction products. The yield of dimers
Allylic dithioacetal as a propene-1,3-Zwitterion synthon. Regioselective conversion of C-S bonds in allylic dithioacetals into C-C bonds

Reaction of allylic dithioacetals with organocuprate or organolithium reagent followed by treatment with a variety of alkyl electrophiles gives the corresponding E and Z isomeric mixture of vinyl sulfides in good yield. Further cross coupling with a Grignard reagent in the presence of NiCl2(dppe) affords the corresponding alkylation products in good yield. In general, the Grignard reagent having the same alkyl group as the R2 substituent in 1 is employed so that the stereochemical problem in coupling products can be lifted.
