Derivatives of cis-NPCl2(NSOCl)2 and (NPCl2)2NS0Cl, Part XIII [1] Methyl- and Ethylamino Derivatives of the Ring System cis-NPCl2(NSOX)2 with X = Chlorine and Fluorine

“…In contrast to the results obtained by Klingebiel and Heider [4,5] we found that the cis-and transisomers have quite different Ö 31 P values (Table I).…”

“…Recently Klingebiel et al reported the isolation of a mixture of isomers of the mono derivatives of as-NPCl2(NSOCl)2 on reaction with, among others, methyl-and ethylamine [4]. Heider et al reported the preparation of a mixture of isomers of the monomethyl-and monoethylamino derivatives of c{s-NPCl2(NSOF)2 from reactions with silylamines [5].…”

The crystal and molecular structure of NPCl2(NSOF)2 at –160°C

“…Recently the six-membered rings (I; X=C1) and (II; X--CI) have been synthesized (van de Grampel & Vos, 1963;Baalmann, Velvis & van de Grampel, 1972) and a number of derivatives prepared (Baalmann & van de Grampel, 1973a, b;Klingebiel, Lin, Buss & Glemser, 1973;Heider, Klingebiel, Lin & Glemser, 1974). A structure determination of (I; X--C1) (van de Grampel & Vos, 1969) showed that the N-S bond lengths in the S-N-P-N-S section differ slightly from those in the S-N-S section of the ring and that the N-P bonds are relatively long.…”
