Lahrech, Mokhtar,Hacini, Salih,Parrain, Jean-Luc,Santelli, Maurice
, p. 3395 - 3398 (1997)
β-Trimethylsilyl allenes have been prepared in fair to good yields from allylsilanes by successive dibromocarbene addition and rearrangement of the cyclopropylidenes. In the case of 3,6-bis(trimethylsilyl)cyclohexa-1,4-diene, insertion of dibromocarbene o

Paragraph 0205; 0380-0381, (2020/01/12)
The invention belongs to the field of, asymmetric synthesis, and discloses a method for catalyzing asymmetric cross- coupling to synthesize: an alkyne, and the L method comprises, the following steps, of A: preparing B a cuprous, salt and C a: ligand; preparing a catalyst; adding a base; reacting the compound with the compound with the compound; and reacting the compound with the compound. Of these, one of them, X is selected from the group consisting of, R halogens. 1 Optionally substituted heteroarylsulfonylcyanamide groups selected from the, group consisting, of optionally substituted, phenyl groups In-flight vehicle, R6 Trialkyl silyl groups or alkyl radicals, R2 Cycloalkyl radicals optionally substituted with an, optionally substituted alkyl, (CH radical2 )n R4 Multi,layer chain, n=0-10,R saw blade4 A group selected, from, the group consisting of phenyl, alkenyl, aralkynyls, noonyloxy,and, noonylsulfonylsulfonylsulfonylsulfonylsulfonylsulfonylsulfonylsulfonylsulfonylsulphonylsulphonylsulphonylsulphonylsulphonylsulphonylsulphonylsulphonylsulphonylsulphonylphenyl disiloxy-radicals. R3 A ligand, selected from hydrogen or any of the functional groups, is selected from the group consisting of, hydrogen and any L other functional group. The method, R disclosed by the, A invention has the, advantages of good catalytic, R ’ effect, wide application range. and high catalytic efficiency, and the, method disclosed by the, invention has the. advantages of good catalytic effect, wide application range and high catalytic efficiency.

supporting information, p. 2199 - 2203 (2013/05/21)
New saturated abnormal N-heterocyclic carbene complexes of gold(I) have been prepared by a 1,3-dipolar cycloaddition of an in situ generated azomethine ylide with an isocyanogold(I) choride. A series of different substituents on the nitrogen atom of the 1
Scope and limitation of the [1,2]-phenylsulfanyl (PhS) migration in the synthesis of tetrahydrofurans and tetrahydropyrans from common triol precursors
House, David,Kerr, Fraser,Warren, Stuart
, p. 2652 - 2662 (2007/10/03)
Scope and limitation of the [1,2]-phenylsulfanyl (PhS) migration in the synthesis of tetrahydrofurans and tetrahydropyrans from common triol precursors were discussed. Triols containing three secondary hydroxy groups were rearranged using either toluene-p
Novel generation of azomethine imines from α-silylnitrosamines by 1,4- silatropic shift and their cycloaddition
Washizuka, Ken-Ichi,Nagai, Keiko,Minakata, Satoshi,Ryu, Ilhyong,Komatsu, Mitsuo
, p. 8849 - 8853 (2007/10/03)
Novel and facile generation of azomethine imines from α- silylnitrosamines and subsequent cycloaddition with dipolarophiles leading to a variety of pyrazole derivatives have been developed. The key to the reaction is a 1,4-silatropic shift caused by stron
