endo-Attack on co-ordinated norbornadiene; crystal structure of di-µ-chloro-bis(endo-3-phenylnorbornen-2-yl-endo-palladium)

Reaction of diphenylmercury with dichloronorbornadiene)palladium gave di-µ-chloro-bis(endo-3-phenylnorbornen-2-yl-endo-palladium) which was characterised by a crystal structure determination; a mechanism for its formation is suggested by analogy with the reactions of dichloro(norbornadiene)platinum and Ph2Hg.
