COPPER(I) IODIDE CAS7681-65-4Use of 1 copper iodide is very wide, can be used as catalyst in organic synthesis, resin modifier, artificial rainfall agent, the cathode ray tube cover, and iodine in iodized salt source. In the presence of 1,2- or 1,3- two amine ligands, copper iodide can catalyze aryl bromide, bromide heterocyclic compounds and vinyl bromide into the corresponding iodide reaction. The general reaction was carried out in two dioxane solvent, sodium iodide iodide as a reagent. Aryl iodides in general than the corresponding chloride and iodide lively, therefore, copper iodide can be catalyzed coupling reaction of a series of halogenated hydrocarbons involved, such as Heck reaction, Stille reaction, Suzuki reaction and Ullmann reaction. 2- bromo -1- octene -3- alcohol and 1- 8-nonynoic in two chloride double (three phenyl phosphine) palladium (II), there are two under cuprous chloride and triethylamine, coupling reaction of 7- methylene -8- sixteen carbon -6- alcohol. 2 is used as a catalyst for organic reactions, anode X-ray tube cover, also used as animal feed additives, copper iodide can be used for the measurement of mechanical and mercuric iodide with high bearing temperature indicator. 3 in many reactions of Grignard reagents in copper iodide as catalyst, with dry Wiff rearrangement.

TERT-BUTYLACETYL CHLORIDE CAS7065-46-5Pivaloyl chloride is a kind of very important acylation reagents, mainly used as pharmaceutical intermediates, in many amides and phenols lipid drug preparation as the main raw material; it has been used in hydroxylamine benzyl penicillin and cephalosporin benzyl hydroxylamine, cefazolin, Dipivalyl epinephrine and other drug production. It is also used as the intermediates of pesticide production, such as chloro pivaloyl chloride.
