Li⁺-Catalyzed Radical Polymerization of Simple Terminal Alkenes

Gas-Phase Lithium Cation Basicity: Revisiting the High Basicity Range by Experiment and Theory

“…Lithium salts are also used in conjunction with aprotic dipolar solvents for cellulose dissolution and as reaction media [6][7][8][9][10]. Further examples of condensed-phase applications can be found in the domain of catalysis by weakly coordinated lithium cation [11][12][13][14][15] and hydrogen storage [16][17][18][19][20]. Analytical mass spectrometry makes use of the formation of gas-phase adducts with metal cations (a process often called cationization), and Li + has been extensively examined in this regard.…”

Ethynylmonocarba-closo-dodecaborates: M[12-HCC-closo-1-CB11H11] and M[7,12-(HCC)2-closo-1-CB11H10] (M=Cs+, [Et4N]+)

“…Functionalized monocarba-closo-dodecaborate anions are used as building blocks in a variety of applications [1][2][3][4][5], for example in ionic liquids [6,7] catalysis [8][9][10][11][12][13][14][15], pharmaceuticals [16,17] and polymers [18,19]. A consequence of the constantly growing demand for functionalized monocarba-closo-dodecaborate anions is the increasing search for efficient procedures for the derivatization of the {closo-1-CB 11 } cage [1][2][3][4][5].…”

Strong Bases and Weak Anions in Catalytic C–H Insertion Reactions of Vinyl Carbocations

“…Further, 2-substituted pinacol boronic ester, anisole and protected aniline benzosuberone derivatives were successfully converted to their corresponding tricyclic styrene products (17)(18)(19) in 48 to 68% yield. Similarly, 2-halogenated benzosuberonyl triflates provided the desired styrene products (20)(21) in 72 and 82% yield. Functionalization at other positions of the fused aryl system afforded tricyclic styrene products (22)(23)(24)(25) in good to excellent yields (77-96%).…”

“…Inspired by work from Michl and others, we hypothesized that Li cations, paired with WCAs, could serve as Lewis acids capable of converting vinyl triflates into reactive vinyl cations [20][21][22] . To evaluate this hypothesis, we considered cyclooctenyl triflates (e.g.…”
