2-Allyloxy-1,2-oxaborolane (V), readily obtained by hydroboration of allyl alcohol with borane reagents such as KBH4HOAc, was used as a key reactant in the synthesis of a series of 2-oxygen derivatives of 1,2-oxaborolane. 2-Allyl-1,2-oxaborolane (XXIII) and 2-hydro-1,2-oxaborolane dimethylsulfide complex (XXIV), prepared from the reaction of V with allylmagnesium bromide and dimethylsulfideborane
,容易通过用硼烷试剂例如KBH烯丙醇的硼氢化得到的2-烯丙氧基-1,2- oxaborolane(V)4 HOAc,被用作反应物键在一个系列的第1 2-氧衍生物的合成, 2-氧杂硼烷。分别由V与烯丙基溴化镁和二甲基硫代硼烷络合物(BMS)反应制得的2-烯丙基-1,2-氧杂硼烷(XXIII)和2-氢-1,2-氧杂硼烷二甲基硫配合物(XXIV)也用作一些低级的2-烷氧基-1,2-氧杂硼烷的反应性中间体。描述了从V到1,2-氧杂硼烷的2-氧衍生物的五种方法和其他可能的途径。
