Rotational isomerism in N-(N-heteroaryl)arenesulphenamides
Abstract
N-(1,2-Dihydro-2-oxoquinolin-1-yl)-N-(1-methylallyl)-4-chlorobenzenesulphenamide (5) has previously been isolated in two stereoisomeric forms. From examination of a number of analogues of (5), it is concluded that the phenomenon which allows isolation of these stereoisomers is restricted rotation around the N–N bond.
