  p -Cyano substituted benzophenone as an excellent photophore for one-electron oxidation of DNA

  摘要：

  Novel DNA-photocleaving molecule 1 consisting of a p-cyano substituted benzophenone photophore and an alkyl amino side chain was developed. DNA cleavage by 1 under photoirradiation conditions occurred selectively at 5' side G of 5'GG3' sequence after hot piperidine treatment. Photoirradiation of deoxyguanosine at 312 nm in the presence of 1 efficiently produced imidazolone as a predominant product. (C) 1998 Elsevier Science Ltd. All rights reserved.

  efficient method for the synthesis of various aryl ketones by palladium‐catalyzed desulfinative addition of aromatic sulfinic acid sodium salts to various nitriles is described (see scheme). Aromatic and aliphatic nitriles are successfully reacted with arenesulfinic acid sodium salts to form aryl ketones in good yields.

  The desulfitative synthesis of aryl ketones from nitriles was also compared to the corresponding transformation starting from benzoic acids. Comparison of the energy profiles indicates that the free energy requirement for decarboxylation of 2,6-dimethoxybenzoic acid and especially benzoic acid is higher than the corresponding desulfitative process for generating the key aryl palladium intermediate. The
