Boron chloride reaction with, phosgene

The reaction of phosgene with copper has been used to purify boron(III) chloride (see Section 9.1.2.2) [1218a]. Copper does not react with phosgene at room temperature [735], but does react between 260 and 400 C, with an activation energy of 100 kJ mol, to give copper(I) chloride [809] ... 

The reactions of amines and amine hydrochlorides with phosgene in the gas-liquid phase are reported to be catalyzed by numerous compounds such as morpholine [74], boron trifluoride [75], aluminum chloride [76], N,N-dialkylcarbamates [77], N,N-dialkylamides [78, 79], tetraalkylureas and thioureas [78-80], hexamethyl-phosphoramide [78], as well as activated carbon [81]. 

Chlorodifluoroamine has been prepared by reaction of difluoro-amine with boron trichloride,1 phosgene (carbonyl chloride),2 or hydrogen chloride 2 treating a mixture of sodium azide and sodium chloride with fluorine 3 reaction of chlorine trifluoride with ammonium fluoride 4 reaction of chlorine with diflu oro-amine in the presence of potassium fluoride 5 and photolysis of tetrafluorohydrazine and sulfinyl chloride (thionyl chloride).6...
