The indigoid dyes, thioindigo (TI), N,N'-diacetylindigo, (NDI) and oxalylindigo (OI), all undergo reduction upon irradiation of the dyes in the presence of electrondonors such as triethylamine (TEA) or N-benzyl-1,4-dihydronicotinamide (BNAH). Product analysis by NMR and high-resolution mass spectrometry has shown that the products for TI and NDI are the formal H/sub 2/ adducts TIH/sub 2/ and NDIH/sub
