Isolation of a Stable 1-Iridabicyclo[3.2.0]hepta-1,3,6-triene and Its Reversible Transformation into an Iridacycloheptatriene
文摘
Reaction of the iridacyclopentadiene complex 2 with 2-butyne yields a mixture in equilibrium of the iridacycloheptatriene 3 and a novel 1-iridabicyclo[3.2.0]hepta-1,3,6-triene, 4.
