We present herein a high yield, highly selective catalytic synthesis of vinylboronate esters (VBEs), including 1,1-disubstituted VBEs, from alkenes without significant hydrogenation or hydroboration, using the simple catalyst precursor, trans-[RhCl(C

Rhodium(I) catalysed diboration of (E)-styrylboronate esters: molecular structures of (E)-p-MeO–C6H4–CHCH–B(1,2-O2C6H4) and p-MeO–C6H4–CH2C{B(1,2-O2C6H4)}3

Diboration of the styrylboronate esters (E)-p-R–C6H4–CHCH–Bcat (1) (R=H, (1a) MeO (1b); cat=1,2-O2C6H4), with B2cat2 in the presence of a variety of rhodium phosphine catalysts gives predominantly either p-R–C6H4–CH2C(Bcat)3 (2), which c

Synthesis, characterisation and molecular structure of [Rh(COE)2(acac)] (COE=cyclooctene, η2-C8H14), an important starting material for the preparation of rhodium catalyst precursors

Autor: Andrés E. Goeta, Edward G. Robins, Todd B. Marder, R. Benjamin Coapes, Jacquelyn M. Burke, Judith A. K. Howard, Stephen A. Westcott

Publikováno v: Journal of Organometallic Chemistry. 649:199-203

The compound [Rh(COE) 2 (acac)] ( 1 ) is a catalyst precursor in its own right, and a starting material for the preparation of other catalyst precursors for use in a variety of reactions such as hydroboration, diboration and the addition of arylboron

Phosphine promoted substituent redistribution reactions of B-chlorocatechol borane: molecular structures of ClBcat, BrBcat and L·ClBcat (cat = 1,2-O2C6H4; L = PMe3, PEt3, PBut3, PCy3, NEt3)†

Publikováno v: Journal of the Chemical Society, Dalton Transactions. :1201-1209

In order to evaluate the potential for side reactions when using B-chlorocatechol borane (ClBcat) in stoichiometric or catalytic transformations involving metal phosphine complexes, we examined the interaction between ClBcat and a series of PR3 compo

Rhodium catalysed dehydrogenative borylation of vinylarenes and 1,1-disubstituted alkenes without sacrificial hydrogenation--a route to 1,1-disubstituted vinylboronates

Autor: Rhodri Ll. Thomas, Fabio E. S. Souza, Todd B. Marder, R. Benjamin Coapes, Jonathan J. Hall

Publikováno v: Chemical communications (Cambridge, England). (5)

The complex trans-[Rh(Cl)(CO)(PPh3)2] (1) is an efficient catalyst precursor for the dehydrogenative borylation of alkenes without consumption of half the alkene substrate by hydrogenation, giving useful vinylboronate esters including 1,1-disubstitut
