Under the catalysis of only 3 mol% of Br2 at room temperature, indoles reacted rapidly with isatins to form bio- logically important 3,3-bis（indole-3-yl）indoline-2-（1H）-ones with high efficiency and wide substrate scope. More- over, we demonstrated that p-toluenesulfonic acid （TsOH） could serve as a surrogate to catalyze this transformation.

办理股权投资刑民交叉案件应当本着坚持鼓励市场交易与维护交易安全的价值共识,准确界分刑民案件。针对股权转让、对赌协议、股东协议、股权代持常见股权投资刑民交叉案件类型,可以从非法占有目的、投资风险责任、案涉财产性质、股东行使权利方面构建刑民案件判定基准。在遵循原理上,从法秩序统一性原理和违法判断相对性规则出发,将民事上合法及民事上不法但不具有刑事违法性的行为不认定构成犯罪;对进入刑事程序的刑民交叉案件,需要认识“先刑后民”“刑民并行”的先天弊端,积极运用“先民后刑”模式,防止将民事案件错误定性为刑事案件。
