The uncatalyzed reaction of C3-substituted cyclopropanes 1b-d with benzeneselenenyl chloride 3 leads to 1-ethyl 4-methyl 2-(phenylseleno)butanedioates 5b-d while the unsubstituted 1a gives the 3-phenylseleno derivative 6a. Formation of 5b-d occurs regio-

The reaction of ethyl 2,2-dimethoxycyclopropanecarboxylates 1-3 with lead tetraacetate (Pb(OAc)4, LTA) in benzene leads to the oxidative scission of the C1-C2 bond. Monoalkylated fumaric acid diesters 4 and 5 are obtained from 3-alkylcyclopropanes 1 and 2, respectively, along with dimeric species for which we propose the unusual anhydride bis-acetal structure 6 or 7, respectively. Reaction of 3,3-dimethylcyclopropane 3 with LTA produces the 3-acetylsuccinate derivative 8 as the sole reaction product.
Ring-opening reactions of cyclopropanes. Part 6. A facile synthesis of dialkyl sulfenylbutanedioates

The reaction of cyclopropanes 1 with sulfenyl chlorides 2 readily affords 2-sulfenylbutanedioates 3 and/or their 3-sulfenyl analogues 5, which are compounds of applicative and biological interest.
Stereospecific Alcohol Elimination From Dialkyl Mesaconates Under Electron Impact: Another Example of a Hidden Hydrogen Transfer
Bornstein, Daniel,Weisz, Adrian,Mandelbaum, Asher
, p. 225 - 228 (2007/10/02)
Under electron impact dimethyl and diethyl mesaconates give rise to abundant +. and +. ions, respectively.The geometrically isomeric citraconates yield +. and +. ions.Mixed methyl ethyl mesaconates eliminate both methanol and ethanol.These findings, together with the results of a deuterium labelling study, indicate that the elimination of alcohol from the molecular ions of the mesaconates is partially preceded by a hidden hydrogen transfer step.
