Question
Chapter 27, Problem 27.26P
Interpretation Introduction
(a)
Interpretation: The product formed on thermal electrocyclic ring opening of the given compounds is to be predicted.
Concept introduction: Electrocyclic reactions involve ring opening or ring closure in a conjugated polyene. According to Woodward-Hoffmann rules, the polyene containing even number of bonds in thermal conditions undergoes reaction in conrotatory fashion and polyene containing odd number of bonds undergo reaction in disrotatory fashion.
Interpretation Introduction
(b)
Interpretation: The product formed on photochemical electrocyclic ring opening of the given compounds.
Concept introduction: Electrocyclic reactions involve ring opening or ring closure in a conjugated polyene. According to Woodward-Hoffmann rules, the polyene containing even number of bonds in photochemical conditions undergoes reaction in disrotatory fashion and polyene containing odd number of bonds undergo reaction in conrotatory fashion.
