A method for the Pd-catalyzed arylation of ammonia with a wide range of aryl and heteroaryl halides, including challenging five-membered heterocyclic substrates, is described. Excellent selectivity for monoarylation of ammonia to primary arylamines was achieved under mild conditions or at rt by the use of bulky biarylphosphine ligands (L6, L7, and L4) as well as their corresponding aminobiphenyl palladacycle precatalysts (3a, 3b, and 3c). As this process requires neither the use of a glovebox nor high pressures of ammonia, it should be widely applicable.

A scalable and operationally simple decarboxylative trifluoromethylation of (hetero)arenes with easily accessible C6F5I(OCOCF3)2 under photoredox catalysis has been developed. This method is tolerant of various (hetero)arenes and functional groups. Notably, C6F5I is recycled from the decarboxylation reaction and further used for the preparation of C6F5I(OCOCF3)2. The combination of photoredox catalysis and hypervalent iodine reagent provides a practical approach for the application of trifluoroacetic acid in trifluoromethylation reactions.

59564-59-9, New research progress on 59564-59-9 in 2021. Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis, preparation and modification of special coatings, and research on the structure and performance of functional materials.59564-59-9, Name is 3,4-Dihydroquinoxalin-2(1H)-one, molecular formula is C8H8N2O. In a article，once mentioned of 59564-59-9

A series of tetracyclic imidazoquinoxaline analogs was developed which constrain the carbonyl group of the partial agonist 3-(5-cyclopropyl-1,2,4- oxadiazol-3-yl)-5-[(dimethylamino)carbonyl]4,5-dihydroimidazo[1,5- a]quinoxaline (2, U-91571) away from the benzene ring. These analogs orient the carbonyl group in the opposite direction of the previously reported full agonist 1-(5-cyclopropyl- 1,2,4-oxadiazol-3-yl)- 12,12a-dihydroimidazo[1,5- a]pyrrolo[2,1-c]quinoxalin- 10(11H)one (3, U-89267). A number of approaches were utilized to form the ‘bottom’ ring of this tetracyclic ring system including intramolecular cyclizations promoted by Lewis acids or base, as well as metal-carbenoid conditions. The size and substitution pattern of the additional ring was widely varied. Analogs within this series had high affinity for the benzodiazepine receptor on the alpha-aminobutyric acid A chloride ion channel complex. From TBPS shift and Cl- current assays, the in vitro efficacy of compounds within this class ranged from antagonists to partial agonists with only 18a identified as a full agonist. Additionally, several analogs were quite potent at antagonizing metrazole-induced seizures indicating possible anticonvulsant or anxiolytic activity. Unlike 3, analogs in this series did not have high affinity for the diazepam insensitive alpha6beta2delta2 subtype. These results suggest that either constraining the carbonyl group away from the benzene ring or the greater planarity that results from the additional cyclic structure provides analogs with partial agonist properties and prevents effective interaction with the alpha6beta2delta2 subtype.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. 59564-59-9, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 59564-59-9, in my other articles.

A unique concept for the intermolecular denitrogenative annulation of 1,2,3,4-tetrazoles and alkynes was discovered by using a catalytic amount of Fe(TPP)Cl and Zn dust. The reaction precludes the traditional, more favored click reaction between an organic azide and alkynes, and instead proceeds by an unprecedented metalloradical activation. The method is anticipated to advance access to the construction of important basic nitrogen heterocycles, which will in turn enable discoveries of new drug candidates.

In the past decades, C?H oxidative olefination of indole at C-2, C-3, C-4 and C-7 positions was well addressed. We report here a rhodium-catalyzed NH-indole-directed ortho C?H bond olefination of 2-arylindoles. This cross-dehydrogenative-coupling proved to be broad in substrate scope, tolerating a variety of functional groups. The synthesis of 6H-isoindolo[2,1-alpha]indoles via rhodium-catalyzed ortho C?H olefination and subsequent intramolecular aza-Michael reaction of 2-arylindoles was also demonstrated.

Phosphorus compound prepared by reaction of triphenylphosphine with trichloroisocyanuric acid was found to be applied to chlorination of nitrogen-containing pi-deficient heteroaromatics. As self-decomposition of the chlorinating reagent hardly proceeds, the reagent is more useful than phosphorus compound prepared by triphenylphosphine and N-chlorosuccinimide.
