Cyanohydrin carbonates were also readily prepared using 5-10 mol% of TTMPP as an organocatalyst. http://www.mdpi.com/1420-3049/14/9/3353/ Wed, 02 Sep 2009 00:00:00 CEST Molecules 2009-09-02 14 9 Article 3353 3359 1420-3049 Tris(2,4,6-trimethoxyphenyl)phosphine (TTMPP): Efficient Catalysts for the Cyanosilylation and Cyanocarbonation of Aldehydes and Ketones 2009-09-02 doi: 10.3390/molecules14093353 Satoru Matsukawa Izumi Sekine Ayumi Iitsuka http://www.mdpi.com/1420-3049/14/7/2594/ Calix[4]pyrrole (1), calix[2]m-benzo[4]pyrrole (2), 10α,20β- and 10α,20α- bis(4-nitrophenyl)-calix[4]pyrroles 3 and 4, respectively, were found to exhibit various organocatalytic activities in the diastereoselective vinylogous addition reaction of 2-trimethylsilyloxyfuran (TMSOF, 7) to aldehydes. The γ-hydroxybutenolide products are obtained in fairly good yields and with moderate diastereoselectivity. The structures of the catalysts, as well as the reaction conditions, strongly influence the efficiency of the reaction. http://www.mdpi.com/1420-3049/14/7/2594/ Wed, 15 Jul 2009 00:00:00 CEST Molecules 2009-07-15 14 7 Article 2594 2601 1420-3049 Calixpyrrole Derivatives: “Multi Hydrogen Bond” Catalysts for γ-Butenolide Synthesis 2009-07-15 doi: 10.3390/molecules14072594 Grazia Cafeo Margherita De Rosa Franz H. Kohnke Annunziata Soriente Carmen Talotta Luca Valenti http://www.mdpi.com/1420-3049/13/12/3236/ The oxidative dehydrogenation of dihydroarenes catalyzed by 2,3-dichloro-5,6-dicyano-benzoquinone(DDQ) and NaNO2 with dioxygen is reported. The combination of DDQ and NaNO2 showed high efficiency and high selectivity, compared with other benzoquinones and anthraquinones, e.g., >99% conversion of 9,10-dihydroanthracene with 99% selectivity for anthracene can be obtained at 120 °C under 1.3 MPa O2 for 8 h. Excellent results were achieved in the oxidative dehydrogenation of variety of dihydroarenes. http://www.mdpi.com/1420-3049/13/12/3236/ Thu, 18 Dec 2008 00:00:00 CET Molecules 2008-12-18 13 12 Article 3236 3245 1420-3049 Organocatalytic Oxidative Dehydrogenation of Dihydroarenes by Dioxygen Using 2,3-Dichloro-5,6-dicyano-benzoquinone (DDQ) and NaNO2 2008-12-18 doi: 10.3390/molecules13123236 Wei Zhang Hong Ma Lipeng Zhou Zhiqiang Sun Zhongtian Du Hong Miao Jie Xu
