Synthesis of buta-1,2,3-trienes possessing the 2-pyridyl unit, and a new synthesis of P2I4
Abstract
The first examples of cumulenes which possess the 2-pyridyl unit have been prepared; isomeric 1,4-diphenyl-1,4-di-(2-pyridyl)butatrienes, as well as tetra-(2-pyridyl)butatriene, have been characterized.
