Could go either way: the addition of nucleophiles to the parent 1,2-dihydro-1,2-azaborine and subsequent quenching with an electrophile generates novel substituted 1,2-azaborine derivatives. Mechanistic studies are consistent with two distinct nucleophilic aromatic substitution pathways depending on the nature of the nucleophile.
亲核试剂与母体 1,2-二氢-1,2-氮杂硼烷加成,然后用亲电试剂猝灭,生成新型取代的 1,2-氮杂硼烷衍生物。机理研究表明,根据亲核试剂的性质,存在两种不同的亲核芳香取代途径。
