Selective B-B bond activation in an unsymmetrical diborane(4) by [(Me3P)4Rh-X] (X = Me, OtBu): a switch of mechanism?

6 May, 2015 - 23:17

Dalton Trans., 2015, 44,8600-8604
DOI: 10.1039/C5DT00618J, CommunicationC. Borner, K. Brandhorst, C. Kleeberg
The unsymmetrical diborane(4) pinB-B((MeN)2(C6H4)) reacts with [(Me3P)4Rh-X] (X = Me, OtBu) giving predominantly either [(Me3P)4Rh-Bpin] or [(Me3P)3Rh-B((MeN)2(C6H4))] depending on X. At low temperatures in the presence of excess PMe3 the unprecedented equatorial boryl complex [(Me3P)4Rh-B((MeN)2(C6H4))] is formed.

The chlorinating behaviour of WCl6 towards [small alpha]-aminoacids

6 May, 2015 - 23:17

Dalton Trans., 2015, 44,8729-8738
DOI: 10.1039/C5DT00518C, PaperMarco Bortoluzzi, Fabio Marchetti, Maria Grazia Murrali, Guido Pampaloni, Stefano Zacchini
WCl6 behaves as a selective chlorinating agent towards the carboxylic function of primary and secondary [small alpha]-aminoacids. The initial formation of [small alpha]-ammonium acylchloride salts may be followed by HCl elimination and, in the case of L-proline derived species, a clean cyclization reaction.
