Although controlling both the position of the double bond and E:Z selectivity in alkene isomerization is difficult, 1 is a very efficient catalyst for selective mono-isomerization of a variety of multifunctional alkenes to afford >99.5% E-products. Many reactions are complete within 10 min at room temperature. Even sensitive enols and enamides susceptible to further reaction can be generated. Catalyst
The present invention provides a polyvinyl ether compound containing an alkylene glycol or polyoxyalkylene glycol unit and a vinyl ether unit in a molecule and having a molecular weight in the range of 300 to 3,000. It shows high volume resistivity and a high viscosity index, so it can be favorably used as lubricating oil for a compression refrigerator.

corresponding reaction with diethylzinc. Phenylsubstituted cyclopropane was obtained from the reaction of olefin with diethylcadmium and benzal iodide. The reaction was found to favour the syn isomer but less than the corresponding reaction with diethylzinc. Phenylpropadienes were obtained from phenylacetylenes, diethylcadmium and gem-diiodoalkane. On the other hand, in the corresponding reaction with diethylzinc

Photolytically generated tert-butoxyl radicals react with vinyl- and propenyl ethers by hydrogen abstraction and addition to the double bond; the abstraction/addition ratio and the regioselectivity of addition are interpreted in terms of predominant steric interactions.
