The very reactive new compounds (Cd)(SiF3)2 and Cd(CF3)2 have been prepared by cocondensation of cadmium vapour with triflurosilyl and triflucromethyl radicals, 19F n.m.r. spectroscopy showing that Cd(SiF3)2 slowly decomposes at room temperature while Cd(CF3)2 decomposes at +5 °C; the addition of glyme (1,2-dimethoxyethane) at low temperature allowed Cd(SiF3)2· glyme and Cd(CF3)2· glyme to be isolated
