-
Paragraph 0155, (2018/03/25)
Embodiments of the present disclosure provide for Rh(I) catalysts, methods of making alkenyl substituted arenes (e.g., allyl arene, vinyl arene, and the like), methods of making alkyl substituted arenes, and the like.
Copper(i)-catalysed asymmetric allylic reductions with hydrosilanes

A copper(i)-catalysed asymmetric allylic reduction enables a regio- and stereoselective transfer of a hydride nucleophile in an SN2′-fashion onto allylic bromides. This transformation represents a conceptually orthogonal approach to allylic substitution reactions with carbon nucleophiles. A copper(i) complex based upon a chiral N-heterocyclic carbene (NHC) ligand allows for stereoselectivity reaching 99% ee. The catalyst enables a stereoconvergent reaction irrespective of the double bond configuration of the starting materials.
Highly enantioselective and anti -diastereoselective catalytic intermolecular glyoxylate-ene reactions: Effect of the geometrical isomers of alkenes

An efficient method for the synthesis of homoallylic alcohols with high enantioselectivities and anti-diastereoselectivities via an In(III)-catalyzed intermolecular glyoxylate-ene reaction has been developed. The geometrical isomers of alkenes were shown to have different reactivities. Only the isomers of the alkenes having a proton β-cis to the substituent reacted in this catalytic system.

A group of modified (salen)Cr(III)Cl complexes with bulky benzylic substituents in the 3,3'-position of the salicylidene moiety have been successfully applied for the asymmetric nitroaldol reaction. The readily accessible complex bearing 3-phenylpent-3-yl groups (2 mol %) leads to β-nitro alcohols in up to 92% yield and 94% ee.
Hydrogen peroxide oxidation of polysubstituted pyrylium salts: Formation of enol esters and furans
Balaban, Teodor Silviu,Hiegemann, Monika
, p. 9827 - 9840 (2007/10/02)
2,4,6-Trialkylsubstituted pyrylium salts 1 have been known to afford 2-acyl-3,5-dialkyl-furans 2 in moderate yields (30 - 45%). Oxidation of these salts in buffer solutions (pH = 3-4.5) increased the yields of acylfurans to 75%. In contrast, tetra- and pe
Collision-induced Dissociations of Substituted Benzyl Negative Ions in the Gas Phase. The Elimination of C4H4
Currie, Graeme J.,Bowie, John H.,Massy-Westropp, Ralph A.,Adams, Gregory W.
, p. 403 - 408 (2007/10/02)
The major collision-induced dissociation of PhEt2 involve the losses of H, H2, and CH4.Loss of H occurs from the phenyl ring, H2 is eliminated principally by the process while methane is lost by the stepwise process in which t
