Abstract

Diene-for-diene substitutions occur on reaction of the title complexes [Ru(η5-C7H11)(η4-C7H12)L]BF4 (L  tBu with cyclohexa-1,4-diene to give [Ru(η5-C6H7)(η4-C7H12)L]BF4 (L  tBuNC (19), CO (20)), and on react : η2-C8H12)(CNtBu)]BF4(26). All the apparent pentadienyl-for-pentadienyl substitutions are suggested to occur via initial dis
