Abstract Reactions of thiophenol and 16 of its derivatives with chloroacetonitrile afforded arylthioacetonitriles IVb-XXb which were treated with hydroxylamine and gave arylthioacetamidoximes IVa-XXa. Compounds VIIa-IXa, XIIa, XVIa and XVIIIa exhibited antireserpine activity in the test of ptosis in mice and compounds IXa and XVIIa in the test of reserpine hypothermia in mice.
