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 ...
532–32–1 NaC 7 H 8 SO 3: sodium tosylate: 657–84–1 NaC 8 H 7 O 2: sodium phenylacetate: 114–70–5 NaC 8 H 9 SO 3: sodium xylenesulfonate: 1300–72–7 NaC 8 H 15 O 2: sodium caprylate: 1984–06–1 NaC 18 H 36 O 2: sodium stearate: 822–16–2 NaCl: sodium chloride: 7647–14–5 NaClO: sodium hypochlorite: 7681–52–9 NaClO 2 ...
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.
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 .

Negligible kinetic isotope effect with fully deuterated reactants ( k H / k D =1.07). Hence, it is inferred that hydride transfer is not rate-determining. Significant competitive isotope effect with C 2 H 2 D 2, ( k H / k D = ~1.9), suggests that rate determining step be prior to formation of acetaldehyde.
Three sixteenths of the Cu atoms are bonded to two near OH groups at 1.93 Å and four stretched OH groups at 2.20 Å to form an axially compressed (2+4) octahedral [Cu(OH) 6], and the remaining one sixteenth of the Cu atoms are bonded to six equivalent OH groups at 2.12 Å to form a regular octahedral [Cu(OH) 6].
