Stepwise dimerization of double [2 + 2] reaction in the co-crystals of 1,5-bis(4-pyridyl)-1,4-pentadiene-3-one and phloroglucinol: a single-crystal to single-crystal transformation
摘要: A double [2 + 2] reaction was shown to occur in a crystal manner an O–H⋯N hydrogen-bonded co-crystal and found stepwise manner, i.e. one site reacts at time.
