3- fluorophenyl 4-methylphenyl

Olah et al.466 observed immediate formation of protonated benzenesulfinic acid upon addition of SO2 to benzenium ion formed in H SO3F-Sb I 5-SO2C11 solution at —78°C. Based upon this observation, Laali and Nagvekar467 developed a method for the synthesis of aromatic sulfoxides [Eq. (5.169)]. Product formation was interpreted in terms of dehydration of protonated benzenesulfinic acid followed by nucleophilic attack by the aromatic to the formed arenesulfinyl cation. Mixed sulfoxides (4-fluorophenyl-4-methylphenyl and 4-fluorophenyl-3-trifluoromethyl sulfoxides) were also prepared by sequential addition of the two aromatics. The direct synthesis of symmetric diaryl sulfoxides in high yields (room temperature, 2—48 h, 50-95%) has been reported through the electrophilic activation of thionyl chloride with triflic acid.468... 

Similarly prepared were the corresponding diphenyl, bis[4-methylphenyl], bis 4-hromophenyl], and bis[3-fluorophenyl] derivatives4. 

An alternative to the use of silyl protection in RNA synthesis employs modified acetals such as l-(2-fluorophenyl)-4-methoxylpiperidin-4-yl (Fpmp) and l-(2-chloro-4-methylphenyl)-4-methoxylpiperidin-4-yl (Ctmp) groups. An improved synthesis of the enol ethers required to introduce these protecting groups has been devised. ...

Preparative Methods by the oxidation of thiourea or amino-iminomethanesulfinic acid (formamidinesulfinic acid) with peracetic acid. Many substituted aminoiminomethanesulfonic acids can be prepared in the same way. 2 Others have utilized hydrogen peroxide with sodium molybdate as a catalyst to oxidize the corresponding thioureas to a variety of monosubsUtuted aminoiminomethanesulfonic acids the substituents include phenyl, 2-methylphenyl, 4-fluorophenyl, / -propyl, cyclohexylmethyl, S-a-methylbenzyl, cyclooctyl, and benzhydiyl. ...
