The kinetics of Ru(III) catalyzed oxidations of urea, methylurea and ethylurea by sodium N-bromo-p-toluenesulfonamide, also known as bromamine-T (BAT), in HCl solution has been studied at 30掳C. The reaction rate shows a first-order dependence each on [BAT], [amide] and [Ru(III)] ...
, N,N -dimethyl-2-tribromoger-myloxypropionamide ( 3a ), ( S )-2-tribromogermyloxypropionpyrrolidide (( S )- 3b ), and N,N -dimethyl- O -(tribromogermyl)mandelamide ( 3c ), respectively. X-ray diffraction study was performed for tribromides 3a , ( S )- 3b , and 3c , ...
Recently, we have reported that the haloboration reaction of 1-alkynes with haloboranes provides synthetically useful 2-halo- 1-alkenylborane derivatives (I) directly, which contain two versatile functions, boron and halogen, in the molecules. Actually, it was demonstrated that such derivatives ...
Fifteen substituted amides (hydrazides) of N-acyl-5-bromo(3,5-dibromo)anthranilic acids were synthesized. Potentiometric titration was used to measure ionization constants for each compound, and quantum chemical parameters were calculated. Four correlational equations were obtained linking ionization ...
N-[2-Phenylthio- or 2,2-bis(phenylthio)ethenyl]-α-bromoalkanamides 5, upon treatment with Bu 3SnH in the presence of AIBN, undergo radical cyclization in a 4- EXO- TRIG manner to give β-lactams 6. Similar treatment of enamide 11B, prepared from L-threonine, afforded two ...
N-Bromoamides catalyze effectively the aziridination of electron-deficient as well as electron-rich olefins using chloramine-T (N-chloro-N-sodio-p-toluenesulfonamide) as a nitrogen source under ambient conditions to afford the corresponding aziridines in good to excellent yields.[Copyright &y& ...
