The decatungstate W10O324- homogeneous photocatalyzed oxygenation of tetrasubstituted alkenes has been mechanistically studied. In all cases, allylic hydroperoxides are the major products. The primary inter- and intramolec
REACTIVITY OF THE ACIDS OF TRIVALENT PHOSPHORUS AND THEIR DERIVATIVES. PART III. THE =P-O- IONS IN REACTION WITH ACTIVATED ALKYL BROMIDES. ATTACK ON BROMINE vs ELECTRON TRANSFER

The mechanism of reductive debromination in the course of the reaction of sodium dialkyl (diaryl) phosphites as well as the sodium salt of dibenzylphosphine oxide with activated alkyl bromides in THF has been investigated.Probable mechanisms namely SET and X-philic substitution are discussed.The cyclopropyl system was chosen for the study of this reaction.The results of the carried out experiments (unrearranged products, no influence of light) suggest that the cyclopropyl radical intermediate (if it is formed) does not paticipate in the product-determining step ofthe reductive debromination under the action of the =P-O- ions.Key words: Bromocyclopropanes, reductive debromination, dialkyl phosphites, diaryl phosphites, dibenzylphosphine oxide, SET, X-philic substitution.

The reaction of ethyl diazoacetate with arsaalkenes 8 and 9, leads to diazaarsole 3 and diazocompounds 10 and 11. Diphenyldiazomethane addition follows a different course leading to alkenes 23 and 24, possibly through a transient arsirane.
ETUDE DE LA REACTION CHLOROCARBENE-ACETALS DE CETENES. I. SYNTHESE D'ESTERS α,β-ETHYLENIQUES.

, p. 2643 - 2652 (2007/10/02)
The reaction of chloro, chloromethyl and chlorophenyl carbenoids with ketene alkylsilylacetals has been studied.Excellent yields of cyclopropanation were observed and the unstable chlorocyclopropanone acetals formed were thermally rearranged in high yield into α-substituted α,β-ethylenic esters.This new method for the synthesis of unsaturated esters appeared complementary of the known-ones.
