A method was developed for preparation of alkynyl peroxides from terpene and steroid aldehydes and ketones by reaction of lithium peroxyacetylides with the corresponding aldehydes and ketones followed by treating the intermediate lithium alcoholates with acyl chlorides.

The initiating activity of acetylenic peroxides in polymerization of styrene was studied. The kinetic parameters of the polymerization and its initiation were calculated. The effect exerted by the structure of radicals on the initiating activity of peroxides was evaluated.

Lithium peroxyacetylides were reacted with Paraform to obtain lithium peroxyalcoholates. The latter react with 4,4'-biphenyldicarboxylic and 2,2'-sulfonyl-4,4'-biphenyldicarboxylic dichlorides, yielding peroxy-contaming esters. Lithium peroxyacetylides react with 4,4'-biphenyldicarboxylic and 2-methoxy- and ;2.2'-sulfonyl-4,4'-biphenyldicarboxylic acids to form acetylenic biphenyldihydroxytetraperoxides.

A series of peroxy-containing tertiary acetylenic alcohols were obtained by reactions of lithium peroxyacetylides with cycloheptanone, cyclododecanone, and (-)-R-carvone. Thermal stability of the products was estimated by thermal analysis and quantum-chemical calculations.
