The photochemical decarbonylation of diphenylcyclopropenone (DPCP) to diphenylacetylene (DPA) proceeds with remarkable efficiency both in solution and in the crystalline solid state. It had been previously shown that excitation to the second electron

Methods are described for the synthesis of bis-diazene precursors of catenated tetraradicals. Photodeazetation in a low-temperature matrix of the N-tosylpyrrole member of the series (13) gives mainly the monodeazetated biradical 34, which is characte

Photolysis of the tetrahedrane Fe2(CO)6(mu-S2) at 450 +/- 35 nm in a Nujol matrix at low temperatures gives an isomer characterized by its nu(CO) infrared frequencies. Comparison of these experimental frequencies with those calculated by density func
