The reactions of perfluoro-aza-propene CF3NCF2 with an excess of oxygen difluoride OF2 and the fluorination of bis(trifluoromethyl)-hydroxylamine (CF3)2NOH are discussed. Additionally, we present density functional calculations (B3LYP/6-31G*) on bis(trifluoromethyl)-hypofluorite (CF3)2NOF, which clearly show that this molecule is a model substance for the discussion of negative hyperconjugation.

Thiobenzophenone, 9-thiocarbonylfluorene and carbonyl sulphide react with the mercurial, Hg2, to form HgS and the compounds Ph2C2, (C6H4)2C2 and 2CO respectively.The last compound is also formed as the major product on mixing the mercurial with carbon disulphide.With thiophosgene, reaction occurs to form HgCl2 and a mixture of the compounds (CF3)2NSCOCl and (CF3)2NSCOON(CF3)2, which are thought to arise by rearrangement of the intermediates (CF3)2NOC(S)Cl and 2CS.A similar rearrangement may also occur during the reactions of thiobenzoyl chloride and aryl chlorothionoformates with the mercurial but the product mixtures from these reactions are more complex and pure compounds have not been isolated.Reaction between thiophosgene dimer and the mercurial results in a simple chlorine exchange to afford the 1,3-dithietane 2cyclo2S>.The low temperature reaction of thiophosgene with (CF3)2NO gives a thermally unstable product believed to be (CF3)2NOCCl2S(O)ON(CF3)2, while the similar reaction with thiobenzophenone appears to give (CF3)2NOCPh2SON(CF3)2, which decomposes above 0 deg C.

The initial product from reaction of the oxyl (CF3)2N-O. with hexafluoroisopropylideneimine is the substituted imine (CF3)2C=N-O-N(CF3)2 (isolated in 81percent yield) which, via further oxyl attack at carbon, gives the compounds (CF3)2CO, (CF3)2N-NO, (CF3)2N-O-N(CF3)2, and (CF3)2N-O-C(CF3)2N+(O-)=N-C(CF3)2-O-N(CF3)2.Oxyl attack on hexafluoroacetone oxime affords as major products (CF3)2CO, (CF3)2NH, and (CF3)2N-O-NO.The oxyl reacts with hexafluoroacetone anil to yield a hexaoxyl adduct, with hexafluoroacetone hydrazone to afford the diazoalkane (CF3)2CN2 (100percent), and with hexafluoroacetone azine to give the bis-1:4-adduct (CF3)2N-O-C(CF3)2-N=N-C(CF3)2-O-N(CF3)2 (100percent).Thus, initial radical attack of the oxyl invariably takes place at carbon in the series of imines studied.
