[Problem] To provide an organoboron compound-containing reagent for organic synthesis reactions which undergoes no trimerization with dehydration, does not necessitate activation with a base, and is stable and highly active.
[Means for Solving Problems] The reagent for organic synthesis reactions contains an organic triol borate salt represented by any of the general formulae (I) to (III) and general formula (XVI): (wherein R
1
represents alkyl, alkenyl, etc.; R
2
represents optionally substituted alkyl, alkenyl, alkynyl, etc. or represents hydrogen; m
+
represents an alkaline metal ion, phosphonium ion, or given ammonium ion; M
2+
represents an alkaline earth metal; X represents halogen or alkoxide; Y represents an alkali metal ion, etc.; A represents optionally substituted methylene; and n represents an integer).
[问题] 提供一种含有有机硼化合物的试剂,用于有机合成反应,该试剂不会发生脱水三聚体化,无需碱激活,稳定且活性高。
[解决问题的方法] 用于有机合成反应的试剂包含由通式(I)至(III)和通式(XVI)中的任一表示的有机三醇硼酸盐,其中R1代表烷基、烯基等;R2代表可选择取代的烷基、烯基、炔基等,或代表氢;m+代表碱金属离子、磷酰离子或给定的铵离子;M2+代表碱土金属;X代表卤素或烷氧基;Y代表碱金属离子等;A代表可选择取代的亚甲基;n代表整数。
