Two chromatography-free and eco-friendly protocols have been developed to synthesize aryl tosylates and mesylates by the tosylation and mesylation of the corresponding hydroxyarenes, respectively. These protocols are superior to other known ones regarding

(Chemical Presented) The mixed-ligand system NiCl2(dppp)/dppf is shown to be an effective catalyst for the neopentylglycolborylation of ortho-, meta-, and para-substituted electron-rich and electrondeficient aryl mesylates and tosylates. The ad
A novel synthesis of aryl mesylates via one-pot demethylation-mesylation of aryl methyl ethers using a mixture of phosphorus pentoxide in methanesulfonic acid
Kaboudin, Babak,Abedi, Yaghoub
experimental part, p. 2025 - 2028 (2009/12/26)
A simple, efficient, and new method has been developed for the synthesis of aryl mesylates via one-pot demethylation-mesylation of aryl methyl ethers. Treatment of a variety of aryl methyl ethers with a mixture of phosphorus pentoxide in methanesulfonic a

A series of macrocyclic piperazinone compounds with dual farnesyltransferase/geranylgeranyltransferase-I inhibitory activity was prepared. These compounds were found to be potent inhibitors of protein prenylation in cell culture. A hypothesis for the binding mode of compound 3o in FPTase is proposed.
A simple preparation of aryl methanesulfonates by thermal decomposition of dry arenediazonium O-benzenedisulfonimides in methanesulfonic acid

Aryl methansulfonates 3 (18 examples) were easily prepared by thermal decomposition of dry arenediazonium o-benzenedisulfonimides 1 in methanesulfonic acid (2). The reactions were carried out at temperatures between 60 and 120°C for times between 0.5 and 8 h. The aryl methanesulfonates were obtained in reproducible yield of 70-90%, with few exceptions. In all cases the o-benzenedisulfonimide (4) could be recovered in good yields which can then be reused to prepare the salts 1. When thermal decomposition of salts 1 was carried out in trifluoromethanesulfonic acid (5) at 90-120°C for 1-2 h, aryl trifluoromethanesulfonates 6 were obtained in 73-78% yield (3 examples).
