Neuere Untersuchungen an Halogeniden und Chalkogeniden des Phosphors
ABSTRACT The article reviews the formation and reactions of sulphur-containing halogenphosphazenes. The emphasis rests on solvolysis reactions with alcohols and different acids. The mechanisms of these reactions are discussed. Different rearrangement reactions are described, where S -alkyl or N -alkyl compounds are formed. If P 3 N 3 F 5 — is used as a substituent unstable compounds are stabilized and new inorganic ring systems are formed. In addition to sulphur compounds some routes are described for the preparation of selenium derivatives.
