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.

All four diastereomers of a typical saturated oligoisoprenoid, 4,8,12-trimethylnonadecanol, are made by an iterative three-step cycle with the aid of traceless thionocarbonate fluorous tags to encode configurations. The tags have a minimum number of total fluorine atoms, starting at zero and increasing in increments of one. With suitable acquisition and data processing, each diastereomer exhibits characteristic chemical shifts of methyl resonances in its 1H and 13C NMR spectra. Together, these shifts provide a basis to predict the appearance of the methyl region of the spectrum of every stereoisomer of higher saturated oligoisoprenoids.
Radical OfC transposition: A metal-free process for conversion of phenols into benzoates and benzamides

We report a metal-free procedure for transformation of phenols into esters and amides of benzoic acids via a new radical cascade. Diaryl thiocarbonates and thiocarbamates, available in a single high-yielding step from phenols, selectively add silyl radicals at the sulfur atom of the CdS moiety. This addition step, analogous to the first step of the Barton-McCombie reaction, produces a carbon radical which undergoes 1,2 OfC transposition through an O-neophyl rearrangement. The usually unfavorable equilibrium in the reversible rearrangement step is shifted forward via a highly exothermic C-S bond scission in the O-centered radical, which furnishes the final benzoic ester or benzamide product. The metal-free preparation of benzoic acid derivatives from phenols provides a potentially useful alternative to metal-catalyzed carbonylation of aryl triflates.
