Apuntes jurídicos sobre el paisaje lingüístico en Euskal Herria

This paper is a study of place-names and signs in the Basque Country from the point of view of language law. These are matters that relate to both the status and corpus of language and contribute to the formation of the language landscape,» After a brief historical introduction, the author focuses on the factors that bear on signs and the language 1andscape: the cornpetence factor and the language factor. The description of the latter leads the author to a discussion of the existing language system, in which the Spanish and Basque sharing official status does not necessarily entail the obligation to use both languages at the same time. Using this discussion as a frame of reference, the au- thor analyses place-names, traffic signals and signs. As for place-names, the existing rules are deemed rigid and lacking in ambition, in that they do not pursue the dissemination of official Basque forms. In traffic signaIs, Basque has to appear alongside Spanish, which is required by Spanish legislation, although this bilingualism excludes place-names that have an official Basque form only. With regard to signs, the author analyses public premises, companies licensed to provide public services and the private sector. For public premises there is no specific regulation, but the status of Basque as an autochthonous language, together with the identification and informatíon purposes of signs, could support the exclusive use of this language, According to the author , companies licensed to provide public services should observe the same language system as the goverment and therefore promote the use of Basque. Finally, in the private sector, the author upholds the legitimacy of measures to promote Basque language use such as tax allowances and exemptions in advertising and commercial signs.

Synthetic scope and DFT analysis of the chiral binap-gold(I) complex-catalyzed 1,3-dipolar cycloaddition of azlactones with alkenes

he 1,3-dipolar cycloaddition between glycine-derived azlactones with maleimides is efficiently catalyzed by the dimeric chiral complex [(S-a)-Binap.AuTFA](2). The alanine-derived oxazolone only reacts with tert-butyl acrylate giving anomalous regiochemistry, which is explained and supported by Natural Resonance Theory and Nucleus Independent Chemical Shifts calculations. The origin of the high enantiodiscrimination observed with maleimides and tert-butyl acrylate is analyzed using DFT computed at M06/Lanl2dz//ONIOM(b3lyp/Lanl2dz:UFF) level. Several applications of these cycloadducts in the synthesis of new proline derivatives with a 2,5-trans-arrangement and in the preparation of complex fused polycyclic molecules are described.
