An efficient catalytic system of a zinc cluster and tetrabutylammonium iodide (TBAI) was developed for cyclic carbonate synthesis from epoxides and carbon dioxide (CO 2 ) without the use of any organic solvents under very mild conditions (25 1C, 1 atm), even in the presence of impurities such as water and air. Electrophilicity of the central Zn(II) ion, the number of trifluoromethyl groups, nucleophilicity and leaving ability of the anion of alkylammonium salts, and various reaction parameters have a great effect on the catalytic activity of the bifunctional catalyst. Therefore, this solvent-free process represents an environmentally friendly example for the catalytic conversion of CO 2 into value-added chemicals and also has the potential to contribute towards decreasing atmospheric CO 2 emission from the burning of fossil fuels.

The tetrakis[(hetero)phenanthryl]methanes 9 have been synthesized from tetrakis(p-iodophenyl)methane (1) in a twostep sequence consisting of a Heck aryl vinylation to give the tetrakis[β-(aryl)-p-styryl]methanes 3 and subsequent oxidative photocyclization. The absorption and emission spectra of the stilbene derivatives 3 showed significant electronic coupling of the four branches both in the ground and in the excited states. According to cyclic voltammetry, the electronrich dimethylamino (3c) and the electroneutral thienyl systems (3d) displayed a rapid, cooperative oxidative fragmentation that could be partially suppressed at high scan rates. In the ferrocenyl systems (3g), the organometallic frag-
