Abstract

A ring R is called right SNF-rings if every simple right R-module is N-flat . In this paper

Selective copper-catalysed atom transfer radical addition (ATRA) in water under environmentally benign conditions

“…In addition, we employed 2 wt% Tween 20/H 2 O (comparable to 16 mM) as our solvent because this concentration is higher than the critical micelle concentration (CMC) of Tween 20 (∼0.05 mM). 27,28 It is also the concentration at which the copper complex ( 1b ) can be dispersed in and resulted in a relatively higher substrate conversion (Table S1†).…”
