摘要:The synthesis of a variety of 2-oxindoles bearing an all-carbon quaternary center at the pseudo benzylic position has been achieved via a ‘transition-metal-free’ intramolecular dehydrogenative coupling (IDC). The construction of 2-oxindole moieties was carried out throug...

摘要:... Transition metal-catalyzed decarboxylative CuAAC and dehydrogenative cross coupling reactions are combined in a single flask and achieved good yields of the respective triazoles (up to 97% yield). This methodology is more convenient to produce the complex polycyclic molecules...

摘要:Abstract(#br)A cross dehydrogenative coupling strategy for allylation of benzylanilines promoted by DDQ is reported, which uses nonmetallic quinone DDQ as an oxidant in the allylation of N-benzylanilines under mild conditions. C–C bond with high selectivity and activity was ...

摘要:Abstract(#br)An iron-catalyzed oxidative dehydrogenative coupling of ethers with aryl tetrazoles has been developed. A wide variety of tetrazoles and ethers survived the reaction conditions to deliver the corresponding hemiaminal derivatives in moderate to good yields.

摘要:Abstract(#br)Ethane, ethene, ethyne and hydrogen are obtained in good yields via dehydrogenative coupling of methane in the presence of active carbon as a catalyst. The product yield is increased by supporting metal on active carbon.

摘要:Abstract(#br)The first synthesis of rigid pentacyclic NORPHOS derivatives by a tandem cross-coupling/cross-dehydrogenative-coupling according to the Catellani reaction protocol is reported. Mediated by palladium complexes of C,P-chelating monophosphine ligands, the readily av...

摘要:Abstract(#br)Base-free catalytic acceptorless dehydrogenative homo-coupling of alcohols to esters under neat conditions was investigated using a combined organometallic synthesis and kinetic modelling approach. The considered bifunctional ruthenium aliphatic PNP complexes ar...

摘要:Abstract(#br)Silane alcoholysis of triethylsilane (Et 3 SiH) with alcohol (ROH) with the help of CpFe(CO) 2 Me ( 1 ) has been achieved to produce triethylsilyl ether (ROSiEt 3 ) under the thermal condition. For some alcohols, the iron complex served as a catalyst. A 16e silyl iro...

摘要:... However, despite of tremendous progress in the field the direct olefination of C(sp3)–H bonds using primary alcohols via an acceptorless dehydrogenative coupling (ADC) is not developed. Such an ADC reaction is highly environmentally benign as it produces dihydr...

摘要:... Recently, a variety of reactions of inactivated cyclic ethers (THF, THP and dioxane) and acyclic ethers with various coupling partners have been reported. Despite the absence of phenyl rings and high oxidation potentials, these ethers worked efficiently under oxidative condi...
