Copper dimethoxide

The diffuse reflectance spectrum of d copper dimethoxide showed broad asymmetric bands with a maximum in the range 13 800-16 000 cm and these bands were assumed... 

Similar to the d" chromium dimethoxide, the d copper(n) alkoxides also exhibit temperature-dependent magnetic susceptibility. " The magnetic moments of copper dimethoxide and diethoxide at room temperature were reported to be in the range 1.07-1.23 B.M. which were less than the spin only value of 1.73 B.M. This abnormal behaviour was attributed to be due to the highly polymeric structure of copper(ii)... 

A suspension of polymeric cupric dimethoxide in pyridine reacts with CO2 to yield the cupric methyl carbonate. The CO2 moiety is, however, very labile the insertion could be reversed by heating the reaction mixture at 80" under a stream of nitrogen [SO]. Another reversible carbon dioxide carrier was found in copper(I) rerr-butoxide, which was stabilized by rerr-butyl isocyanide. The rerr-butyl carbonato complex was formed during the reaction with CO2 [811. Carbon dioxide also reacts with ROCu(PPh3)2 0 produce (ROCOj)Cu(PPhj>3, Hydrolysis or thermolysis of these alkylcarbonato complexes gives the binuctear carbonato copper (I) complex (PPhj>2 CuCK Oj Cu(PPhj)2, which can be further convened into the bicarbonate complex f(HC)C02)Cu(PPh3)3] by reaction with CO2 in moist solvents [82],...
