Efficient Pd-catalyzed amination reactions for heterocycle functionalization.
The Pd-catalyzed amination of unprotected benzo-fused heterocycles is reported, which allows for greater flexibility and efficiency in the modification of this important class of molecules. The generality of these simple and efficient procedures is demonstrated through the synthesis of a wide variety of structural types.
متن کاملMolybdenum Catalyzed Ammonia Borane Dehydrogenation: Oxidation State Specific Mechanisms
Though numerous catalysts for the dehydrogenation of ammonia borane (AB) are known, those that release >2 equiv of H2 are uncommon. Herein, we report the synthesis of Mo complexes supported by a para-terphenyl diphosphine ligand, 1, displaying metal-arene interactions. Both a Mo(0) N2 complex, 5, and a Mo(II) bis(acetonitrile) complex, 4, exhibit high levels of AB dehydrogenation, releasing ove...
متن کاملHomogeneous, titanocene-catalyzed dehydrocoupling of amine-borane adducts.
Transition metal catalysis represents a relatively unexplored but potentially useful route to form bonds between main group elements. Previous work in the area of amine-borane adduct dehydrocoupling has exclusively employed late transition metal (e.g., Rh) catalysts which were found to predominantly operate via a heterogeneous mechanism. Herein, we present a new, early transition-metal-catalyze...
متن کاملPd-mediated synthesis of substituted benzenes fused with carbocycle/heterocycle.
A new Pd-catalyzed one-pot multicomponent coupling reaction for the construction of benzene ring fused with carbocycle or heterocycle under a Cu-free condition is described.
متن کاملSynthesis and antitubercular activity of heterocycle substituted diphenyl ether derivatives.
Despite being an ancient disease, tuberculosis (TB) remains the leading single-agent infectious disease killer in the world. The emerging serious problem of TB control and clinical management prompted us to synthesize a novel series of heterocyclic substituted diphenyl ether derivatives and determine their activity against the H37Rv strain of Mycobacterium. All ten compounds inhibited the growt...
