7778-85-0 Usage

Uses

1,2-Dimethoxypropane has been used in the preparation of 1,4-dioxanes.

Check Digit Verification of cas no

The CAS Registry Mumber 7778-85-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,7 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7778-85:
(6*7)+(5*7)+(4*7)+(3*8)+(2*8)+(1*5)=150
150 % 10 = 0
So 7778-85-0 is a valid CAS Registry Number.

On the origin of nitrogen-containing promoters in the cobalt-catalyzed methoxycarbonylation of epoxides

He, Jianghua,He, Lin,Li, Zhen,Liu, Jianhua,Liu, Mengli,Wang, Fang,Xia, Chungu,Yun, Dong,Zeng, Bo

The detailed promotion mechanism of nitrogenous compounds in the cobalt-catalyzed methoxycarbonylation of epoxides has not been studied to date. Herein, we present the intrinsic correlation between nitrogenous promoters and activity and selectivity in the alkoxycarbonylation of epoxides by a comprehensive in situ IR spectroscopy and DFT studies. In situ IR spectroscopy confirmed the acid-base neutralization of the nitrogenous promoters and HCo(CO)4, resulting in reduction of the acidity of the catalyst. With the reduced acid-derived activity for formation of ethers as by-products, the selectivity of desired esters was increased. DFT calculations showed that a nitrogenous base could facilitate the methanolysis of cobalt-acyl species with lowered activation energy, which is considered to be the rate-determining step in the catalytic cycle. As a result, the reaction activity towards carbonylation was also improved by nitrogenous promoters. The present studies will provide new insights to the long-term confusing problems in epoxides carbonylation.

Anodic Oxidation. Part 17. The Formation of Alkyl Methyl Carbonates in the Hofer-Moest Reaction in Methanol

, p. 2927 - 2929 (2007/10/02)

The liquid products from the electrolysis of sodium butanoate in methanol containing methyl sodium carbonate at a graphite anode include propyl and 1-methylethyl methyl carbonates. 1,1-Dimethylethyl methyl carbonate is amongst the liquid products from the electrolysis of sodium 2,2-dimethylpropanoate in methanol at a platinum anode in the presence or absence of methyl sodium carbonate.Typical secondary products derived from propene or 2-methylpropene are also present in the liquid products from each of these electrolyses.
