Preparation and properties of dithiopyrophosphoryl tetrafluoride [F2P(:S)·O·P(:S)F2] and some thiophosphoryl difluoride derivatives
Abstract
Three methods are described for the preparation of dithiopyrophosphoryl tetrafluoride, F2P(:S)·O·P(:S)F2 together with its physical and spectroscopic properties. The reactions between the reagents NaX and dithiopyrophosphoryl tetrafluoride yield the thiophosphoryl difluoride derivatives, F2P(:S)X (X = CN, N3, NCO, NCS, and F) and monothiodifluorophosphates.
