首次合成并分离了手性环三硅氧烷对映体。三(2-丁基)三苯基环三硅氧烷中三个苯基的螺旋桨式排列对(R)-2-丁基的Cotton效应为正,对(S)-2-丁基的Cotton效应为负。
We have synthesized and separated the enantiomer pair of chiral cyclotrisiloxanes for the first time. Three-blade propeller-like alignment of three phenyl groups in tri(2-butyl)triphenylcyclotrisiloxane induced a positive Cotton effect with (R)-2-butyl group, and a negative effect with (S)-2-butyl substituent.
