A fluorinated cobalt(III) porphyrin complex [Co(TPFPP)NTf2·2C2H5OH, where TPFPP=5,10,15,20-tetrakis(pentafluorophenyl)porphyrin, Tf=CF3SO2] promotes hydroalkoxylation of alkynes to give acetals in good to excellent yields. The acetals can be directly functionalized with nucleophiles in a one-pot procedure.

Photostimulated free radical chain reactions between alkoxideions derived from primary alcohols and XCMe2NO2(X = Cl, Br, NO2, PhSO2, N3, or p-ClC6H4S) occur to produce Me2C(OR)2 by a reaction involving the trapping of Me2C(NO2)· by RO–, the decomposition of ROCMe2NO2·– to ROCMe2·, and the oxidation of ROCMe2· to Me2COR+ by XCMe2NO2·
