, p. 157 - 162 (1996)
A phenylnorbornylpalladacycle containing methyl isonicotinate ligands was shown to undergo either ring opening or ring enlargement by reaction with acetylenic compounds to give norbornylalkynes regioselectively and ring-enlarged tetracyclic compounds non-regioselectively. However, in the case of ethyl propiolate regioselective ring enlargement takes place.
Palladium catalyzed multicomponent reactions in ordered sequence: New syntheses of o,o′-dialkylsubstituted diarylacetylenes and diarylalkylidenehexahydromethanofluorenes

Catalytic one-pot reactions of aromatic iodides with alkyl halides, phenylacetylene or diphenylacetylene, potassium acetate or carbonate, norbornene and palladium acetate in DMF or DMA are reported. A high selectivity towards dialkylsubstituted diarylacetylenes and diarylalkylidenehexahydromethanofluorenes, respectively, has been reached.
Palladium Catalyzed Reactions of Organic Halides with Organotin Compounds Involving Insertion of Norbornene. Synthesis of 2,3-Disubstituted Norbornane

, p. 193 - 194 (2007/10/02)
2,3-Disubstituted norbornanes were prepared by the palladium catalyzed reaction of a ternary system composed of organic halide, organotin compound, and norbornene.Aryl and vinyl bromides, and acyl chloride were good substrates, but benzyl and allyl chlorides were not.Vinyl, phenyl, ethynyl, and allyltin compounds were utilizable reagents.
PALLADIUM OR NICKEL-CATALYZED SEQUENTIAL REACTION OF ORGANIC BROMIDES, BICYCLOHEPT-2-ENE OR BICYCLOHEPTA-2,5-DIENE AND ALKYNES

, p. 129 - 138 (2007/10/02)
The reactions of various types of organic bromides with a mixture of bicycloheptene or bicycloheptadiene and alkynes are reported.The products are bicyclic compounds, containing an organic chain and an alkynyl group in adjacent positions.In the presence o
ONE-POT PALLADIUM-CATALYZED SYNTHESIS OF 2,3-DISUBSTITUTED BICYCLOHEPTANES AND BICYCLOHEPT-5-ENES
Catellani, Marta,Chiusoli, Gian Paolo
, p. 4517 - 4520 (2007/10/02)
A new and highly stereoselective palladium-catalyzed synthesis is reported, based on two subsequent insertion of the bicycloheptene system into an aryl or vinylpalladium bond, formed in situ from aryl or vinyl bromides.
