The latter process provides a high-yield route to 1,1-binaphthol: [22] Such compounds are intermediates in the synthesis of BINAP and its derivatives. [20] Copper(II) chloride dihydrate promotes the hydrolysis of acetonides, i.e., for deprotection to regenerate diols [23] or aminoalcohols, as in this example (where TBDPS = tert ...
IR absorption spectrum of copper(I) chloride. Copper(I) chloride, commonly called cuprous chloride, is the lower chloride of copper, with the formula CuCl.The substance is a white solid sparingly soluble in water, but very soluble in concentrated hydrochloric acid.

Simplified diagram of the Copper–Chlorine cycle. The copper–chlorine cycle (Cu–Cl cycle) is a four-step thermochemical cycle for the production of hydrogen. The Cu–Cl cycle is a hybrid process that employs both thermochemical and electrolysis steps.
No H/D exchange effects seen in this reaction. Experiments using C 2 D 4 in water generate CD 3 CDO, and runs with C 2 H 4 in D 2 O generate CH 3 CHO. Thus, keto-enol tautomerization is not a possible mechanistic step. Negligible kinetic isotope effect with fully deuterated reactants ( k H / k D =1.07).
In numerous variants that have been developed, other transition metal salts, including copper(II), iron(III) and cobalt(III) have also been employed. [7] Due to its wide synthetic applicability, the Sandmeyer reaction, along with other transformations of diazonium compounds, is complementary to electrophilic aromatic substitution .

The Gattermann–Koch reaction, named after the German chemists Ludwig Gattermann and Julius Arnold Koch, [7] is a variant of the Gattermann reaction in which carbon monoxide (CO) is used instead of hydrogen cyanide. [8] Unlike the Gattermann reaction, this reaction is not applicable to phenol and phenol ether substrates. [5]
