The better to evaluate the properties and functions of cyanate and thiocyanate radicals as pseudohalogens, efforts have been made in this Laboratory to prepare complete series of compounds containing both halogen and pseudohalogen. The only series previously completed has been that of the silicon chloroisocyanates,'although compounds formulated as PClzNCOI2 POC12SCNJ2 SiC13SCN2 and presumably GeC4Br3 have recently been ...
