Photolysis of p-Toluenesulfonyl Azide and Its Charge-Transfer Complex with Aniline
Hoyle, C. E.,Lenox, R. S.,Christie, P. A.,Shoemaker, R. A.
, p. 2056 - 2061 (1983)
Photolysis of p-toluenesulfonyl azide (1) in p-xylene and cyclohexane gives primarily the products derived from insertion of (p-tolylsulfonyl)nitrene into the solvent.For p-xylene, an unstable intermediate product is formed which decomposes in the dark at room temperature to give both the ring-insertion product and the corresponding p-toluenesulfonamide (2).Photolysis of the ground-state charge-transfer complex between p-toluenesulfonyl azide and aniline gives six products, the major product being the sulfonyl hydrazide 7.Furthermore, formation of the insertion product by reaction with the solvent provides evidence for production of (p-tolylsulfonyl)nitrene from the excited charge-transfer complex.
B(C6F5)3-catalyzed transfer hydrogenation of imines and related heteroarenes using cyclohexa-1,4-dienes as a dihydrogen source
Chatterjee, Indranil,Oestreich, Martin
, p. 1965 - 1968 (2015)
The strong boron Lewis acid tris(pentafluorophenyl) borane, B(C6F5)3, is shown to abstract a hydride from suitably donor-substituted cyclohexa-1,4-dienes, eventually releasing dihydrogen. This process is coupled with the FLPtype (FLP = frustrated Lewis pair) hydrogenation of imines and nitrogen-containing heteroarenes that are catalyzed by the same Lewis acid. The net reaction is a B(C 6F5)3-catalyzed, i.e., transition-metal-free, transfer hydrogenation using easy-toaccess cyclohexa-1,4-dienes as reducing agents. Competing reaction pathways with or without the involvement of free dihydrogen are discussed.
Solid phase synthesis of sulfonamides using a carbamate linker
Raju,Kogan, Timothy P.
, p. 3373 - 3376 (1997)
A method for the synthesis of sulfonamides on a solid support by immobilizing amines through the nitrogen atom using a carbamate linkage is described.
New reactivity of methoxyhydridosilane in the catalytic activation system
Hojo, Makoto,Murakami, Chikara,Fujii, Atsuko,Hosomi, Akira
, p. 911 - 914 (1999)
Hydroxy esters are reduced by trimethoxysilane in the presence of a catalytic amount of lithium methoxide to yield diols, while for simple esters the alcohol exchange reaction takes place preferentially. Through the exchange reaction, lactones, without a hydroxy group are reduced. Tosylimines are also reduced in the system.
The effect of coordination on the reaction of N-tosyl imines with diethylzinc
Gao, Feifeng,Deng, Minzhi,Qian, Changtao
, p. 12238 - 12243 (2005)
The effect of coordination on the reaction of N-tosyl imines and diethylzinc was studied in detail. It showed that there was strong coordination between N-tosyl imine and diethylzinc. Due to this coordination, N-tosyl imines could be reduced directly thro
Copper-boryl mediated transfer hydrogenation of N-sulfonyl imines using methanol as the hydrogen donor
He, Yi,Li, Shi-Guang,Mbaezue, Ifenna I.,Reddy, Angula C.S.,Tsantrizos, Youla S.
, (2021/03/24)
B2Pin2-assisted copper-catalyzed transfer hydrogenation of aromatic sulfonylimines has been achieved, delivering a variety of aryl/heteroaryl sulfonamides in good to excellent yields under mild reaction conditions and with methanol a
Diiodine-Triethylsilane System: Reduction of N-Sulfonyl Aldimines to N-Alkylsulfonamides
Jiang, Jin,Xiao, Lili,Li, Yu-Long
supporting information, p. 291 - 294 (2020/11/09)
Because molecular iodine and hydrosilanes are stable to both air and moisture, reactions using these reagents are easy to operate and require mild reaction conditions. Molecular iodine and a hydrosilane were used to reduce N-sulfonyl aldimines to the corr
