Reaction of phosgene with silicon halides

Silicon(IV) fluoride reacts in a quartz tube with phosgene to give carbonyl chloride fluoride with 100% selectivity and 42% conversion, at 420 C no COFj is formed [377]. 

An equimolar solution of silicon(IV) chloride and phosgene in tetrachloromethane showed no evidence for complex formation, as monitored by infrared spectroscopy [ICIl]. Indeed, i.r. spectroscopy has been used to determine phosgene levels in commercial SiCl  

As silicon(IV) oxide is the only common oxide which is not chlorinated by phosgene (see Section 9.4.4) [360], the reaction between phosgene and silicon(IV) chloride was examined both experimentally and theoretically [654]  

Heating the reagents in sealed tubes up to 540 C, in the dark and under a mercury lamp, provided no evidence for this reaction proceeding to any significant extent, not too surprising
