transformations of unsaturated hydrocarbons, such as alkynes, alkenes, and dienes, mediated by the divalent titanium reagent Ti(O-i-Pr)4/2 i-PrMgX, which proceed via (ν 2-alkene)- or (ν 2-alkyne)-titanium intermediates. Many of these transformations are otherwise difficult or require multi-step reaction sequences. Since Ti(O-i-Pr)4 and i-PrMgX are non-toxic and available in bulk at low price, the reagent satisfies
此帐户描述的不饱和烃的合成转化,如
炔烃,烯烃和二烯烃,通过二价
钛介导的试剂的Ti(O-我-Pr)4 /2我-PrMgX,其进行经由(ν 2 -烯烃) -或(ν 2 -alkyne) -
钛中间体。这些转化中有许多是困难的,或者需要多步反应序列。由于Ti(O- i- Pr)4和i -PrMgX无毒且可廉价批量购买,因此该试剂满足大规模合成所用的条件。
