An iridium-catalyzed, highly efficient, and site-selective deoxygenation of primary, secondary, and tertiary alcohols has been realized, under the assistance of a 4-(N-substituted amino)aryl directing group. Only the hydroxyl adjacent to the directing group can be deoxygenated. The deoxygenation is performed in water, with formic acid as both the promoter and hydride donor. Excellent yields and functionality

selectively. The reaction tolerates a wide range of functional groups (e.g. silanes, boronates, anilines, esters, alcohols, and various heterocycles) and works with various allylicalcohols. Complementary to most current routes for the C3 allylation of an unprotected indole, this method provides access to C2 and C4–C7 allylated indoles. Preliminary mechanistic experiments reveal that the reaction might start
Friedel–Crafts-Type Allylation of Nitrogen-Containing Aromatic Compounds with Allylic Alcohols Catalyzed by a [Mo<sub>3</sub>S<sub>4</sub>Pd(η<sup>3</sup>-allyl)] Cluster
the Friedel–Crafts-type allylic alkylation of nitrogen-containing aromaticcompounds catalyzed by a [Mo3S4Pd(η3-allyl)] cluster is achieved. With a 3 mol % catalyst loading in acetonitrile at reflux or 60 °C, a variety of N,N-dialkylanilines and indoles reacted smoothly with allylic alcohols to afford the Friedel–Crafts-type allylation products in good to excellent yields with high levels of regioselectivity

The selective conversion of alcohols to alkanes and alkenes is a captivating but extremely difficult process. Herein, we explored the activity of an acridine-derived SNS–Ru pincer complex in the selective conversion of primary alcohols into both long-chain alkenes and alkanes. Both homo- and cross-coupling reactions provide good yields of the desired products with excellent selectivity. Various control
