The first topochemical 1,6-polymerization of a triene has been observed. The required supramolecular structure for this polymerization was achieved by the pi-pi stacking of the isonicotinate functionality. The crystal environment of this polymerization reaction controlled both the molecular and supramolecular structure of the polymer and allowed its structure to be determined by single-crystal X-ray diffraction.

Benylic, allylic, and propargylic alcohols, as well as diols, can be oxidized with o-iodoxybenzoic acid (IBX) in the presence of stabilized Wittig ylide[1] to generate α,β-unsaturated ester in one pot. This is useful when the intermediate aldehydes are unstable and difficult to isolate. *IICT communication no. 4369.

Conjugated trienes 3 and 5 have been prepared by the palladium-catalyzed reaction of alkenes 2 with fumaryl chloride (1) and (E)-5-phenyl-2,4-pentadienoyl chloride (4), respectively, in the presence of N-ethylmorpholine.
The first topochemical 1,6-polymerization of a triene has been observed. The required supramolecular structure for this polymerization was achieved by the pi-pi stacking of the isonicotinate functionality.
