Irradiation of benzonitrile in 2,2,2-trifluoroethanol (TFE) with 254-nm light from low-pressure mercury lamps results in the formation of four addition products, the stereoisomers of 6-cyano-2-(2,2,2-trifluroethoxy)bicyclo[3.1.0]hex-3-ene, 22−25. T

Commercially available 5-methoxysalicylic acid 16 was converted into the o-quinone monoketal 21, which was attached to the enediyne 22, resulting in 23. After protection of the tert-alcohol 24 and conversion of the ester 25 to aldehyde 28, treatment

A Co-catalyzed highly regio- and enantioselective reductive coupling of alkynes and aldehydes has been developed under visible light photoredox dual catalysis. A variety of enantioenriched allylic alcohols have been obtained by using unsymmetrical in

Photolysis of trans-[(cyclam)MnIII(N3)2](ClO4) (1) in methanol at −35 °C with ∼350 nm light produces blue [{trans-[(cyclam)MnV(N)]}2(μ-N3)](ClO4)3·3H2O (2) and dinitrogen (cyclam = 1,4,8,11-tetraazacyclotetradecane). A series of six-coordinate
