873-76-7 Usage
Description
It is usually used as the intermediate in organic synthesis and pharmaceutical industry. Specifically, this chemical can react with o-xylene in the presence of HAuCl4 or AuCl3 at 80 ℃ to generate the corresponding benzylated product.1 Moreover, the acetylation of 4-chlorobenzyl alcohol in presence of catalytic amounts of Ce(OTf)4 has been performed in acetic acid to produce the desired esters in the excellent yields.2 In addition, this chemical may function as the raw material to produce its corresponding carboxylic acids and ketones in good yields through the oxidation reaction by using hydrogen peroxide and cobalt(Ⅱ) complex.3 Besides, the formylation and acetylation of 4-chlorobenzyl alcohol may be carried out in the presence of Silphos [PCl3?n(SiO2)n] in ethyl formate and ethyl acetate.4

Check Digit Verification of cas no
The CAS Registry Mumber 873-76-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,7 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 873-76:
(5*8)+(4*7)+(3*3)+(2*7)+(1*6)=97
97 % 10 = 7
So 873-76-7 is a valid CAS Registry Number.

Hydrogenation of Esters by Manganese Catalysts
Li, Fu,Li, Xiao-Gen,Xiao, Li-Jun,Xie, Jian-Hua,Xu, Yue,Zhou, Qi-Lin
, (2022/01/13)
The hydrogenation of esters catalyzed by a manganese complex of phosphine-aminopyridine ligand was developed. Using this protocol, a variety of (hetero)aromatic and aliphatic carboxylates including biomass-derived esters and lactones were hydrogenated to primary alcohols with 63–98% yields. The manganese catalyst was found to be active for the hydrogenation of methyl benzoate, providing benzyl alcohol with turnover numbers (TON) as high as 45,000. Investigation of catalyst intermediates indicated that the amido manganese complex was the active catalyst species for the reaction. (Figure presented.).

The first mild, in situ, single-pot, high-yielding well-screened copper (II) salt-based catalyst system utilizing the hydrogen surrogacy of sodium borohydride for selective hydrogenation of a broad range of nitro substrates into the corresponding amine under habitancy of water or methanol like green solvents have been described. Moreover, this catalytic system can also activate various functional groups for hydride reduction within prompted time, with low catalyst-loading, without any requirement of high pressure or molecular hydrogen supply. Notably, this system explores a great potential to substitute expensive traditional hydrogenation methodologies and thus offers a greener and simple hydrogenative strategy in the field of organic synthesis.
Redox-active ligand based Mn(i)-catalyst for hydrosilylative ester reduction
Chakraborty, Soumi,Das, Arpan,Mandal, Swadhin K.
supporting information, p. 12671 - 12674 (2021/12/04)
Herein a Mn(i) catalyst bearing a redox-active phenalenyl (PLY) based ligand is reported for the efficient hydrosilylation of esters to alcohols using the inexpensive silane source polymethylhydrosiloxane (PMHS) under mild conditions. Mechanistic investigations suggest a strong ligand-metal cooperation where a ligand-based single electron transfer (SET) process initiates the reaction through Si-H bond activation.
