TL;DR: In this article, a 10-step sequence is described for the conversion of 4methyl-exo-tricyclo [5.1.0 2,6 ] deca-4,8-dien-one (the Pauson-Khand cycloaddition product of norbornadiene with propyne) into 3,3dimethyl-2-[(2-methoxyethoxy) methoxy]-8-(1-methyl-2-oxopropyl) bicyclo [3.3.0] octan-6-
Abstract: A 10-step sequence is described for the conversion of 4-methyl-exo-tricyclo [5.2.1.0 2,6 ] deca-4,8-dien-one (the Pauson-Khand cycloaddition product of norbornadiene with propyne) into 3,3-dimethyl-2-[(2-methoxyethoxy) methoxy]-8-(1-methyl-2-oxopropyl) bicyclo [3.3.0] octan-6-ol. The latter diquinane, formed with complete stereocontrol and well-differentiated functionality, is appropriately substituted to serve as an entry to highly functionalized linearly fused triquinanes, although attempts to close a third five-membered ring via an enolate-epoxide ring-opening proces were unsucessful

TL;DR: In this article, the difference in reactivity between the two processes is discussed in terms of different mechanisms for the two reactions, and the difference of reactivity trends of these two processes are discussed.

TL;DR: In this paper, the replacement of naphthalene ligand in the ruthenium complex [CpRu(C10H8)]+ by halide anions in the presence of 1,5-cyclooctadiene (cod) or norbornadiene(nbd) was determined by X-ray diffraction.

TL;DR: Novel biphotochromic systems containing two norbornadiene moieties in one molecule or one norbornadienyl group in 2-N-(3-phenylnorbornadienes-2-carbonyl)]-N-arylaminomethylene-(2H) benzo[b]thiophenones have been prepared under UV/VIS irradiation as mentioned in this paper.
Abstract: Novel biphotochromic systems containing two norbornadiene moieties in one molecule or one norbornadienyl group in 2-N-(3-phenylnorbornadiene-2-carbonyl)]-N-arylaminomethylene-(2H) benzo[b]thiophenones have been prepared Under UV/VIS irradiation the latter compounds undergo Z/E-isomerktion acompanied by N → O acyl rearrangement and valence isomerization in the norbornadiene fragment Bis-norbornadienyl derivatives upon irradiation convert through stepwise isomerization into corresponding quadricyclanes The back reactions are catalyzed with trifluoroacetic acid at room temperature

TL;DR: In this paper, density functional theory calculations have been employed to understand the bonding and structural features of the key intermediate complexes formed during the catalytic cycle for the hydrogermylation, hydrosilylation and hydrostannation of norbornadiene (nbd) in the photochemical reaction of the tungsten and molybdenum(0) carbonyl complex.
