Syntheses of phenothiazinylboronic acid derivatives - suitable starting points for the construction of redox active materials. Kramer, Christa S.; Zimmermann, Thomas J.; Sailer, Markus; Muller, Thomas J. J. (Department Chemie, Ludwig-Maximilians-Universitat Munchen, Munchen 81377, Germany).Several reagents such as 25015-63-8 is used here. Synthesis, (9), 1163-1170 (English) 2002 Georg Thieme Verlag. CODEN: SYNTBF. ISSN: 0039-7881. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 28, 72 Phenothiazinylboronic acid derivs. as useful building blocks for the construction of oligophenothiazines, are readily synthesized in good yield from brominated phenothiazines by bromine-lithium exchange followed by trapping with trialkyl borate or by palladium-catalyzed borylation with tetra-Me dioxoborolane. The novel class of tetrakis(phenothiazinylphenyl)methanes, showing remarkably large Stokes shifts and a reversible low oxidn. potential, can be prepd. in good yield by Suzuki coupling of tetrakis(p-bromophenyl)methane with phenothiazinylboronic acid deriv. .

Synthesis of benzylboronates via palladium-catalyzed borylation of benzyl halides with pinacolborane

Synthesis of benzylboronates via palladium-catalyzed borylation of benzyl halides with pinacolborane. Murata, Miki; Oyama, Takashi; Watanabe, Shinji; Masuda, Yuzuru ( Department of Materials Science, Kitami Institute of Technology, Kitami 090-8507, Japan). Synthetic Communications, 32(16), 2513-2517 (English) 2002 Marcel Dekker, Inc. CODEN: SYNCAV. ISSN: 0039-7911. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Various benzyl halides were borylated with pinacolborane in the presence of iPr2NEt and a catalytic amt. of PdCl2(PPh3)2 to afford the corresponding benzylboronates in good yields. E.g., PhCH2Cl was added to CH2ClCH2Cl soln. 25015-63-8 is just another one chemical used in this study. of pinacolborane with catalyst PdCl2(PPh3)2/iPr2NEt and stirred at 80° to give 96% yield of PhCH2B(OCMe2CMe2O). .
