Alkynylboronates are employed as a practical and versatile precursor for a variety of π-conjugated organic compounds. In the presence of a Cu(I) or Cu(II) salt, transformation of alkynylboronates into the corresponding 1,3-diynes upon exposure to air takes place readily in aprotic polar solvents such as DMI.
炔基
硼酸酯用作各种π-共轭有机化合物的实用且通用的前体。在Cu(I)或Cu(II)盐的存在下,
炔烃硼酸酯暴露于空气后,在质子惰性极性溶剂(如
DMI)中容易转化为相应的1,3-二炔。
