Sustainable mining in the European Union: the legislative aspect.

This paper is a review of the community legislation of the European Union ("acquis communautaire") with regard to the mineral extractive industry. It highlights the existing inconsistencies of the acquis, which require correction. Historically, the mining industry has received privileged treatment within the European Community.

Bi-, Tri-, and Tetranuclear Metallomacrocycles Constructed by Metal-Directed Reactions Involving Resorcinol or Hydroquinone or by Addition of Octahedral Metal Centers to Tetrahexylcalix[4]resorcinarene: X-ray Crystal Structure of syn,syn-[Mo{HB(3,5-Me(2)C(3)HN(2))(3)}(NO)(1,4-O(2)C(6)H(4))](3).

The reaction between [Mo(NO)(Tp)I(2)] [Tp(-) = hydrotris(pyrazol-1-yl)borate] and tetrahexylcalix[4]resorcinarene (resH(8)) affords a mixture of metalated macrocycles from which [{Mo(NO)(Tp)}(2)(resH(4))], [{Mo(NO)(Tp)}(3)(resH(2))], and [{Mo(NO)(Tp)}(4)(res)] can be isolated. In the solid state the tetrametalated compound can act as a host for CH(2)Cl(2) which forms a weak hydrogen bond to the oxygen of a coordinated nitric oxide: H.O1 2.

Hydrogen Bonding of CHCl(3) to Coordinated Nitric Oxide in a Binuclear Metallomacrocycle and the Crystal Structures of anti-[Mo(NO){HB(3,5-Me(2)C(3)HN(2))(3)}(2,7-O(2)C(10)H(6))](2).2CHCl(3).CH(2)Cl(2), syn-[Mo(NO){HB(3,5-Me(2)C(3)HN(2))(3)}(2,7-O(2)C(10)H(6))](2).0.67CHCl(3).2.7H(2)O, and syn-[Mo(NO){HB(3,5-Me(2)C(3)HN(2))(3)}(2,7-O(2)C(10)H(6))](2).3(CH(3))(2)CO.

The reaction between [Mo(NO)(Tp)I(2)] {Tp(-) = hydrotris(3,5-dimethylpyrazol-1-yl)borate} and 2,7-dihydroxynaphthalene affords, as its major product, the binuclear complex [Mo(NO)(Tp)(2,7-O(2)C(10)H(6))](2). The reaction appears to proceed under kinetic control so that shorter reaction times afford the syn-isomer (47% yield after 40 min) while longer reaction times allow the anti-isomer (43% yield after 48 h) to be obtained. The molecular structures of anti-[Mo(NO){HB(3,5-Me(2)C(3)HN(2))(3)}(2,7-O(2)C(10)H(6))](2).

5-Methyl-2'-deoxy-4'-thio-alpha-uridine (R)-S-oxide.

The pyrimidine ring of the title compound, C(10)H(14)N(2)O(5)S, is planar to within 0.024 (1) A and makes an angle of 75.46 (10) degrees with the mean plane of the thiosugar ring.
