Cobalester, a natural nontoxic vitamin B12 derivative, was found to catalyse unusual olefinic sp2 C-H alkylation with diazo reagents as a carbene source instead of the expected cyclopropanation.
The first example of a singlet oxygen induced double bond migration during sulfide photooxidation. Experimental evidence for sulfone formation via a hydroperoxy sulfonium ylide
Clennan, Edward L.,Aebisher, David
, p. 1036 - 1037 (2007/10/03)
The first example of the formation of a sulfone concomitant with double bond migration aunng photooxidation of a sulfide is reported. Evidence is presented which demonstrates that the double bond migration is not a result of a prior acid-catalyzed rearrangement of an unrearranged sulfone precursor. This unusual observation is used to argue that the sulfone is formed via rearrangement of a hydroperoxy sulfonium ylide intermediate.
Reactions of α-or χ-Phenylthio Substituted Extended Enolate Anions Derived from Esters
Brownbridge, Peter,Durman, John,Hunt, Paul G.,Warren, Stuart
, p. 1947 - 1958 (2007/10/02)
The title anions are alkylated and acylated (α series only) exclusively at the α position.The α-phenylthio products give χ-phenylthio compounds by the PhS shift and the PhS group may be removed from the products in a number of ways.
EXTENDED ENOLATE IONS FROM γ-PHENYLTHIO-CROTONATE ESTERS
Brownbridge, Peter,Hunt, Paul G.,Warren, Stuart
, p. 3391 - 3394 (2007/10/02)
Substituted γ-phenylthio-crotonate esters (7) can be made by and PhS shifts: they form extended enolate anions which react with electrophiles at the carbon atom α to the carbonyl group and γ to sulphur.
