税收担保是税法上的一项重要制度,但由于税收担保本身的特殊性,使得税收担保的法律属性在理论中难以得到统一的认识。在税收法律关系中,税收担保的法律属性对纳税人的基本权利、税收法定主义的适用范围都有很大影响,而我国相关制度却存在许多漏洞。文章结合纳税人提供担保的原因和税收担保制度的具体内容,对税收担保的法律属性进行了分析,并为我国完善税收担保制度提出了一些建议。

A new cooperative nickel reductive catalysis and N,N-dimethylformamide-mediated strategy for umpolung C–S radical reductive cross coupling of S-(trifluoromethyl)arylsulfonothioates with alkyl halides to produce alkyl aryl thioethers is described. This reaction features excellent selectivity, wide functionality tolerance, broad substrate scope, and facile late-stage modification of biologically relevant *** studies recognize initial generation of an amidyl radical anion via thermoinduced reduction of DMF with Sn, followed by umpolung reduction and single electron transfer of the nucleophilic sulfonyl moiety to form a sulphydryl radical and engage the Ni^(0)/Ni^(Ⅰ)/Ni^(Ⅲ)/Ni^(I) catalytic cycle.
