I ve been told that sodium allyl sulfonate sas and sodium vinyl sulfonate svs are used as brightening agents for nickel electroplating.

Copper vinyl sulfonate.

Sigma aldrich offers a number of divinyl sulfone products. Copper ii sulfate also known as copper sulphate are the inorganic compounds with the chemical formula cu so 4 h 2 o x where x can range from 0 to 5 the pentahydrate x 5 is the most common form. The pentahydrate cuso 4 5h 2 o the most commonly encountered salt is bright blue. Older names for this compound include blue vitriol bluestone vitriol of copper and roman vitriol.

Metz has investigated the use of these dienophiles in the intramolecular diels alder reaction with cyclic dienes and furans to furnish the cyclic sulfonate esters in excellent yields scheme 162 the intermediate trienes often cannot be isolated as. 60 000 q a topics education aloha fun topic 30561 are sulfonate monomers used in electroplating. The transformation is promoted by 3 7 mol of a cu complex generated in situ from a mixture of inexpensive cucl a readily available phosphine or imidazolium salt and kot bu at ambient temperature. Vinyl sulfonate esters are extremely good dienophiles cycloadditions occurring at much lower temperatures than their carboxylate counterparts.
