, p. 929 - 930 (1986)
The Cu(acac)2-catalyzed decomposition of α-diazoacetophenones in the presence of bis(p-methoxy-phenyl) selenide (3) did not give the corresponding selenonium ylide but gave r-l,c-2,t-3-tribenzoylcylopropanes through the successive reaction of the intermed
Palladium-catalyzed suzuki-miyaura cross-coupling of a-halomethyl oxime ethers and site-selective cross-coupling of dihalo derivatives

The cross-coupling reaction of chloro- and bromomethyl oxime ethers with a wide range of aryl-, heteroaryl- and vinylboronic acids in the presence of catalytic palladium complexes with different phosphines has been carried out with good yields (60-98%, 40 examples). Regioselective cross-coupling reactions differentiating between an alkyl or aryl position are achieved from dihalo oxime ethers containing Csp2- and Csp3-halogen bonds using mono- or dicoordinated palladium catalysts such as Pd (dba)2/P (o-tolyl)3 or Pd (PPh3)4. The selective orthogonal functionalization of dihalo oxime ethers is also described. Site-selective transformations allow the introduction of the biaryl motif into dihalo oxime ethers preserving the highly activated alkyl halide moiety vicinal to the oxime group for further transformations. In this context, Z- and E-oxime ethers could be considered as synthetic equivalents of ketones in palladium-catalyzed Suzuki reactions.
Synthesis of 2-benzoyl-3-aryl-N-arylsulphonylaziridines from the reaction of N-arylsulphonylimines with dimethylsulphonium phenacylide - The first example of a functionalized-methylene transfer to azomethines

The first example of phenacyl group transfer from dimethylsulphonium phenacylide to N-arylsulphonylimines to yield 2-benzoyl-1-arylsulphonylaziridines is described.
SYNTHESIS AND SOME REACTIONS OF INDOLO-1,4-OXAZINIUM PERCHLORATES
Kibal'nyi, A.V.,Nikolyukin, Yu.A.,Dulenko, V.I.
, p. 895 - 900 (2007/10/02)
The reaction of acyl perchlorates with 1-phenacylskatole affords the previously unknown 1-R-10-methyl-3-phenylindolo-1,4-oxazinium salts, which undergo recyclization by the action of ammonia to the corresponding indolopyrazines.It is found t
