  Compounds of formula (I) and salts thereof: wherein R1, R2, R3, a, X1, X2, X3, X4, and X5 are as defined hereinbefore. Compounds of formula (I) and salts thereof have been found to inhibit the binding of the BET family of bromodomain containing proteins to, for example, acetylated lysine residues and thus may have use in therapy, for example in the treatment of autoimmune and inflammatory diseases, such as rheumatoid arthritis; and cancers.

  Prototropic tautomerism was used as a tool for the reductive dehalogenation of (hetero)aryl bromides and iodides, or dehalogenative sulfonation of (hetero)aryl chlorides and fluorides, using sodium sulfite as the sole reagent in an aqueous medium. This protocol does not require a metal or phase transfer catalyst and avoids using organic solvent as the reaction medium. This method is especially suitable

  质子互变异构被用作在水介质中使用亚硫酸钠作为唯一试剂的（杂）芳基溴化物和碘化物的还原性脱卤化或（杂）芳基氯和氟化物的脱卤化磺化的工具。该方案不需要金属或相转移催化剂，避免使用有机溶剂作为反应介质。此方法特别适用于容易互变异构的底物（例如2-或4-卤代氨基酚和4-卤代间苯二酚），在温和的反应条件下（≤60°C）会进行脱卤或磺化。由于亚硫酸钠是一种廉价，安全且对环境无害的试剂，因此该方法至少具有三个潜在应用：（i）使用亚硫酸钠作为还原剂对卤素作为保护基进行脱保护；（ii）在温和的反应条件下磺化芳族卤化物，避免使用危险和腐蚀性的试剂/溶剂；（iii）将有毒的卤代芳族化合物转化为危害较小的化合物。
