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.

The program was renamed to National Talent Search Scheme with the NTSE examination now being conducted for classes X, XI, and XII. Currently, the NTSE exam is conducted only for 10th class students in India in two phases with subjects relating to Mental Ability Test and Scholastic Aptitude Test (SAT) for 100 marks each. [6] [7]
Copper(I) iodide reacts with mercury vapors to form brown copper(I) tetraiodomercurate(II): . 4 CuI + Hg → (Cu +) 2 [HgI 4] 2− + 2 Cu. This reaction can be used for the detection of mercury since the white CuI to brown Cu 2 [HgI 4] color change is dramatic.
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].
Atomic Energy of Canada Limited has demonstrated experimentally a CuCl electrolyzer in which hydrogen is produced electrolytically at the cathode and Cu(I) is oxidized to Cu(II) at the anode, thereby combining above steps 1 and 4 to eliminate the intermediate production and subsequent transport of solid copper.
