Conjugated diynes underwent selective mono-titanation with a Ti(II) reagent to give 1:1 diyne-titanium alkoxide complexes, which reacted with proton, aldehyde, and another acetylene to give stereo-defined enynes, enynols, and dienynes.
共轭二炔通过Ti(II)试剂进行选择性单钛化,得到1:1的二炔钛醇盐配合物,该配合物与质子,醛和另一种乙炔反应生成立体确定的炔烃,烯醇和二烯。
