Alkyl sulfone synthesis by C-S coupling reactions.
The vinyl phenyl sulfones can be completely converted to allyl phenyl sulfones with only 0.2 equiv of NaH, suggesting that the second hydride involvement in the above transformation is catalytic. The regioselective control observed in these reactions offers a general method for synthesizing novel vinyl and allyl phenyl sulfones in one step from the same starting materials. The regioselectivity.
Reduction of phenyl vinyl sulphones in dimethylformamide containing phenol as proton donor causes loss of phenylsulphinate ion. The reaction probably involves a series of electron and proton addition steps (74). In absence of a proton source, phenyl vinyl sulphone radical-anion undergoes a dimerization reaction discussed on p. 57. Reactions of.
In organic chemistry, the phenyl group or phenyl ring is a cyclic group of atoms with the formula C 6 H 5. Phenyl groups are closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a functional group. Phenyl groups have six carbon atoms bonded together in a hexagonal planar ring, five of which are.

The CAS number is the substance numerical identifier assigned by the Chemical Abstracts Service, a division of the American Chemical Society, to substances registered in the CAS registry database. A substance identified primarily by an EC or list number may be linked with more than one CAS number, or with CAS numbers that have been deleted.

A halogenmethylsulfonyl moiety is incorporated in numerous active herbicides and fungicides. The synthesis of tribromomethyl phenyl sulfone derivatives as novel potential pesticides is reported. The title sulfone was obtained by following three different syn-thetic routes, starting from 4-chlorothiophenol or 4-halogenphenyl methyl sulfone.
