Joint reactions of alkenes, alkynes, and hydrogen bromide or hydrogen chloride were examined.Ethylene was the only olefin which afforded a crossed cycloadduct, viz. 1-bromo-1-methylcyclobutane (3), in its reaction with propyne and HBr.Reactions of propene with propyne/HBr, with 1-butyne/HCl, and with 2-butyne/HCl as well as reactions of 1-butene with propyne/HBr gave only cyclic and/or acyclic crossover products, which are derived from alkylation of the alkyne by the alkene.Dihalotrialkylcyclobutanes were obtained as cyclic crossover products, which had carbon skeletons composed of two molecules of the acetylene and of one molecule of the olefin used.

In the cases of 2-methylbutane and 2-methylpentane the formation of tertiary sulphochlorides in the sulphochlorination of the parent hydrocarbons could be established by means of 13C-n.m.r.-spectroscopy.The relative rates of the various C-H-bonds in 2-methylbutane, 2-methylpentane and 3-methylpentane in the sulphochlorination reaction were determined.The relative rates of the tertiary C-H-bonds in the sulphochlorination were considerably lower than the corresponding values for the chlorination of the branched-chain paraffins.

In chloroform in the presence of tert-butyl peroxide di-tert-alkoxymethanes from the corresponding tert-alkyl formates, tert-alkyl chlorides, and alkanes; here the chloroform is converted into methylene chloride and 1,1,2,2-tetrachloroethane.The relationships between the accumulation rate of the reaction products and the concentration of acetal, chloroform, and initiator were determined.An unbranched radical-chain mechanism was established for the fragmentation of the acetals with quadratic termination at the tert-alkyl and dichloromethyl radicals.
