✦ Synopsis

In the 2H-chromene series, complexation of the aromatic ring with chromium tricarbonyl, under thermal conditions, is totally regioselective even when aromatic substituents are introduced on the pyran ring. The complexation stabilizes the open form of these photochromic compounds and reduces the thermal bleaching kinetic constant.

Although in the 2H-chromene (benzopyran) series complexation with tricarbonylchromium, under thermal conditions, is totally regioselective, in the naphthopyran series the same reaction cannot be observed. We show here that with tricarbonyl(trispyridine)chromium as complexing agent, in the presence o

The electronic effects of the chromium tricarbonyl fragment on the structure of the benzene ring of (η 6 -C 6 H 6 )Cr(CO) 3 is investigated theoretically using ab initio molecular orbital calculations with electron correlation included by using both Møller-Plesset second-order calculations and densi
