Biradical intermediate in the [2 + 2] photocycloaddition of dienes and alkenes to [60]fullerene.

چکیده
The photocycloaddition of vinylcyclopropanes to C60 yields stereospecifically a five-membered [60]fullerene adduct. These results suggest a biradical intermediate of the [2 + 2] photocycloaddition between dienes or arylalkenes and C60. An electron transfer between the triplet excited state of C60 and the unsaturated substrates precedes the formation of the intermediate.

Cu(I)-catalysed [2 + 2] photocycloaddition of 1,6-dienes embedded in a furano sugar is described in connection to a synthetic approach to an abnormal marine prostanoid tricycloclavulone. An unprecedented influence of remote substituents on the reactivity and stereoselectivity of the photocycloaddition reaction has been uncovered during this investigation. While an alkene substituent inhibits cy...
متن کاملTriplet 1 , 4 = biradical intermediates in the photocycloaddition reactions of enones and N - acylindoles with alkenes
The structures, lifetimes, pathways for decay, and rate constants for formation and reaction of the triplet 1,4-biradicals produced as intermediates in the reaction of the triplet excited states of 2-cyclopentenone and of N-acylindoles with alkenes to produce cyclobutane adducts have been investigated. For the photochemical reaction of cyclopentenone with methoxyand alkyl-substituted alkenes it...

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 کاملThe arene–alkene photocycloaddition
In the presence of an alkene, three different modes of photocycloaddition with benzene derivatives can occur; the [2 + 2] or ortho, the [3 + 2] or meta, and the [4 + 2] or para photocycloaddition. This short review aims to demonstrate the synthetic power of these photocycloadditions.

Atropisomeric 3,4-dihydro-2-pyridones undergo stereospecific [2+2]-photocycloaddition in solution with high stereoselectivity (ee > 98% and de > 96%) in the product. The chiral transfer during phototransformation was rationalized based on the stability/reactivity of the biradical.
