X-ray diffraction study of bis(A-methyl) 1-N-phenylimino-2-hydroxyimid
odithiooxalate 5a and xyimino)-N-(4-fluorophenyl)phenylthioglyoxyimida
te 5b resulting from trapping hydroxynitrilium ions derived from 1-ary
lamino-1-methylthio-2-nitroethenes with MeSH or PhH shows that the thi
oimidate group is E-configured meanwhile the hydroxyimino groups posse
ss the nucleophilic entering group and the OH in the syn configuration
, in agreement with theoretical considerations. (C) 1998 Elsevier Scie
