Synthesis of 1,2-Dioxolanes by Ozonolysis of 1,1-Disubstituted Nonactivated Olefins

, p. 191 - 195 (2007/10/02)
Ozonolyses of the cyclopropyl-substituted olefins 2a, 2b, and 2c do not produce the carbonyl oxides 1a, 1b, and 1c but formaldehyde oxide (1d); 1d can be trapped by the starting olefin and provides the 1,2-dioxolanes 6a, 6b, and 6c, respectively, in ca. 10percent yield.Other dioxolanes and normal ozonides may be obtained by the addition of olefins or aldehydes to solutions of the primary ozonides of 2a and 2b.Key-Words: Ozonolysis / Alkylidenecycloalkanes / Carbonyl oxides / 1,2-Dioxolanes / 1,2,4-Trioxolanes
INTRAMOLECULAR ALKYLATION OF PEROXIDES AND HYDROPEROXIDES; PEROXIDE TRANSFER VIA PEROXONIUM INTERMEDIATES
Porter, Ned A.,Mitchell, John C.
, p. 543 - 546 (2007/10/02)
A series of homologous peroxy-bromides is reacted with silver ion in organic solvents.Cyclic peroxide formation occurs along with peroxide transfer to the carbon originally bearing bromine.A preference for five-membered ring peroxonium ion formation is observed in these intramolecular alkylations.
