Photochemistry of Cyclic Vicinal Tricarbonyl Compounds. Photochemical Reaction of 1,2,3- Indanetrione with 2,3-Dimethyl-2-butene: Hydrogen Abstraction and Photocycloaddition
نویسندگان
چکیده
A irradiação na região do ultravioleta de 1,2,3-indanotriona, em presença de 2,3-dimetil-2buteno, em diclorometano, leva a uma mistura complexa de produtos formados a partir de reações de abstração de hidrogênio, fotocicloadição [2π+2π] (reação de Paternò-Büchi) e fotocicloadição [4π+2π]. A distribuição de produtos é dependente de fatores eletrônicos e estéricos, com estes últimos sendo os responsáveis pelo alto rendimento químico de formação do produto resultante da cicloadição fotoquímica [4π+2π].

Chirogenic [3 + 2]-photocycloaddition reactions of 2-substituted naphthoquinones with cyclic alkenes.
The formal [3 + 2]-photocycloaddition of 2-hydroxy- (2a) and 2-amino-1,4-naphthoquinone (2b) to olefins was studied in various solvents aiming at a possible enantioselective reaction course. The reaction conditions were optimised for irradiation at low temperature in a nonpolar solvent employing external fluorescent lamps as irradiation sources. Best yields for the reaction of 2-hydroxy-1,4-nap...
متن کاملApplications of hydrogen-bond-acceptor templates to direct 'in-phase' reactivity of a diene diacid in the solid state.
The hydrogen-bond-acceptor (HBA) templates 2,3-bis(4-methylenethiopyridyl)naphthalene (2,3-nap) and 1,8-bis(4-pyridyl)naphthalene (1,8-dpn) are used to assemble (E,E)-2,5-dimethylmuconic acid (dmma) in the solid state for an intermolecular [2 + 2] photocycloaddition. Co-crystallisation of 2,3-nap with dmma affords an 1D hydrogen-bonded polymer that is photostable while 1,8-nap affords a 0D hydr...
متن کاملAsymmetric photocycloaddition of naphthamide with a diene using the provisional molecular chirality in a chiral crystal.
N-(2-Methoxy-1-naphthoyl)piperidine afforded chiral crystals by spontaneous crystallization, and the molecular chirality of the crystals was retained after dissolving them in a cooled solvent. An asymmetric photocycloaddition reaction with a diene was performed using the provisional chiral molecular conformation derived from these chiral crystals.
متن کاملConversion of N-Heptane on Pt/Al2O3 Catalyst
Hydrogenation reaction with n-heptane on Pt/Al2O3 catalyst was investigated under the steady state condition in a fixed bed reactor. The catalyst was prepared under a variety of conditions, but the one chosen was non-acidic that is not considered a hydrocracking catalyst. The main objective was to vary the selectivity of n-heptane as a function of reaction variables es...
