Abstract
AbstractCompounds containing the PNCO grouping can be obtained e.g. from phosphorus halides and silver cyanate or esters of N‐chloroiminocarbonic acid and by thermal decomposition of alkoxycarbonylimino‐phosphoranes. The phosphorus (V) isocyanates resemble the “carbon” isocyanates in their chemical properties, whereas the phosphorus (III) isocyanates resemble the phosphorus (III) chlorides. Some of the compounds discussed have insecticidal or cytostatic actions.
