Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 120-61-6, Name is Dimethyl terephthalate, molecular formula is C10H10O4, belongs to esters-buliding-blocks compound, is a common compound. In a patnet, author is Liu, Xin, once mentioned the new application about 120-61-6, COA of Formula: C10H10O4.
Selective Construction of C-C and C=C Bonds by Manganese Catalyzed Coupling of Alcohols with Phosphorus Ylides
Herein, we report the manganese catalyzed coupling of alcohols with phosphorus ylides. The selectivity in the coupling of primary alcohols with phosphorus ylides to form carbon-carbon single (C-C) and carbon-carbon double (C=C) bonds can be controlled by the ligands. In the conversion of more challenging secondary alcohols with phosphorus ylides the selectivity towards the formation of C-C vs. C=C bonds can be controlled by the reaction conditions, namely the amount of base. The scope and limitations of the coupling reactions were thoroughly evaluated by the conversion of 21 alcohols and 15 ylides. Notably, compared to existing methods, which are based on precious metal complexes as catalysts, the present catalytic system is based on earth abundant manganese catalysts. The reaction can also be performed in a sequential one-pot reaction generating the phosphorus ylide in situ followed manganese catalyzed C-C and C=C bond formation. Mechanistic studies suggest that the C-C bond was generated via a borrowing hydrogen pathway and the C=C bond formation followed an acceptorless dehydrogenative coupling pathway.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 120-61-6. The above is the message from the blog manager. COA of Formula: C10H10O4.
