Polymerization of propylene by nonbridged zirconocene complexes

Nonbridged zirconocene dichlorides, (1,2-Me2-4-RC5H2)2 ZrCl2 (R = Me (3), Ph (4), p-FC6H4 (5), 2-furyl (6), 2-thienyl (7), and Fc (8)), and meso- and rac-(1-Me-3-PhC5H3)2ZrCl2 (9 and 10), in the presence of MAO show a high catalytic activity (8.1-17.4 × 106 gPP/molZr · h) in the polymerization of propylene and produce almost an atactic elastomeric polymer of high molecular weight (Mw = 10.5 - 23.2 × 104). In contrast, rac-(1-Me-3-t-BuC5H3)2ZrCl2 (12) shows very low activity and produces a rather high isotactic polymer of low molecular weight.

Gold(I)-Catalyzed Highly Enantioselective [4 + 2]-Annulations of Cyclopentadienes with Nitrosoarenes via Nitroso-Povarov versus Oxidative Nitroso-Povarov Reactions

This work reports gold-catalyzed highly enantioselective nitroso-Povarov reactions between cyclopentadienes and nitrosoarenes in cold dichloroethane, in which nitrosoarenes serve as 4π-electron donors and cyclopentadienes as 2π-donors. High enantioselecti

Gold-catalyzed (4 + 2)-annulations between α-alkyl alkenylgold carbenes and benzisoxazoles with reactive alkyl groups

This work reports new (4 + 2)-annulations of α-alkyl vinylgold carbenes with benzisoxazoles to afford 3,4-dihydroquinoline derivatives with high anti-stereoselectivity. The annulations are operable with carbenes in both acyclic and cyclic forms. This reaction sequence involves an initial formation of imines from α-alkylgold carbenes and benzisoxazoles, followed by a novel carbonyl-enamine reaction to yield 3,4-dihydroquinoline derivatives. This system presents the first alkyl C-H reactivity of α-alkyl gold carbenes with an external substrate.
