Disrotatory fashion
WebFigure 4 shows the orbital array involved in the butadiene to cyclobutene interconversion. It is seen that there are four orbitals in this cyclic array. Thus in the interconversion reactions orbitals 1 and 4 overlap either in a conrotatory or a disrotatory fashion. Also, it is seen that the conrotation involves one plus-minus overlap as drawn ... http://fashiondistraction.com/

WebAn electrocyclic reaction can either be classified as conrotatory or disrotatory based on the rotation at each end of the molecule. In conrotatory mode, both atomic orbitals of the end groups turn in the same direction (such as both atomic orbitals rotating clockwise or counter-clockwise). In disrotatory mode, the atomic orbitals of the end ... WebOct 7, 2009 · Disrotatory bicycle pedals: Irradiation of the title compound in the solid state gives the all-trans isomer directly in a crystal-to-crystal reaction. This threefold cis–trans photoisomerization is proposed to proceed by a two-stage mechanism that is consistent with two simultaneous bicycle-pedal processes occurring in disrotatory fashion about the …

WebIn a conrotatory mode, the substituents located at the ends of a conjugated double bond system move in the same ( clockwise or counterclockwise) direction during ring opening or ring closure. In a disrotatory mode, they move in opposite directions. An example is the conversion of trans -cis-trans-2,4,6-octatriene to cis -dimethylcyclohexadiene ...
