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.
A polyvinyl ether compound (including one having a specified terminal group) having constitutional units each represented by general formula (I) wherein R₃, R₄ and R₅ represent each H or alkyl; R⁶ represents alkylen; R⁷ represents alkyl; and k represents 0 to 10; and a process for producing the same by polymerizing a vinyl ether monomer in the presence of a specified initiator comprising a combination of a Brönsted acid, Lewis acid or organometallic compound with an adduct of a carboxylic acid with water, alcohol, phenol, acetal or vinyl ether. The compound is useful as lubricating oil, etc. A process for producing an ether compound by the reaction of an acetal or ketal represented by general formula (II) with hydrogen in the presence of an acidic substance and a solid catalyst having a hydrogenating ability to convert the group R³³O- or R³⁴O- into a hydrogen atom.
