  An efficient decarboxylative alkylation reaction of β-keto acids with N-benzylic or N-allylic sulfonamides has been developed, for the first time, through sequential cleavage of carbon–nitrogen and carbon–carbon bonds in the presence of 10 mol% of FeCl3.

  The solid acid, tin hydroxide-embedded montmorillonite, catalyzes the unprecedented alkylation of various silicon enolates with primary, secondary and tertiary benzylic alcohols as well as secondary allylic alcohols. The acid catalysis of Sn-Mont was not only higher than that of the other ion-exchanged montmorillonites (M-Mont; M = H, Ti, Fe and Al), but also higher than that of the typical homogeneous

  固体酸，氢氧化锡包埋的蒙脱石可催化各种烯醇硅与伯，仲和叔苄醇以及仲烯丙基醇的空前烷基化。Sn-Mont的酸催化作用不仅高于其他离子交换的蒙脱土（M-Mont； M = H，Ti，Fe和Al），而且高于典型的均相酸催化剂（如BF）3 ·OEt 2，TMSOTf和TfOH。

  The combined use of a halogen bond (XB) donor with trimethylsilyl halide was found to be an efficient cocatalytic system for the direct dehydroxylative coupling reaction of alcohol with various nucleophiles, such as allyltrimethylsilane and trimethylcyanide, to give the corresponding adduct in moderate to excellent yields. Detailed control experiments and mechanistic studies revealed that the XB interaction

  Direct aminations of allylic alcohols, benzylic alcohols, and benzhydrols with electron‐withdrawing (F, Br, I, NO2, or CN) substituents were efficiently catalyzed by aluminum triflate [Al(OTf)3] to afford the corresponding biarylamines in high yield, and the dibromo‐substituted product was further transformed into letrozole.
