AbstractAbstract
[en] The authors have previously discovered that bivalent lanthanides (Ln2+) can form outer-sphere complexes of formula [LnLn](BPh4)2, where L = H2O or acetonitrile (CH3CN). The stability of the complexes decreases on going from H2O to CH3CN. This is directly correlated with the size of these solvent molecules. Clearly the larger the solvent molecule in the inner-sphere, the less stable the outer-sphere complexes. It must be mentioned that analogous complexes are not formed if the size of the solvent is further increased on going to tetrahydrofuran (THF). In aqueous-ethanol, the authors observed outer-sphere complexes with Es2+ in addition to Ln2+. The stability constants β2 varied in the order Yb2+ < Eu2+ < Es2+. Therefore, it seems interesting to determine if the order of the stability constants would change on going to organic solvents

AbstractAbstract
[en] The preparation of acyclic molecules featuring congested stereocenters in a 1,4-relationship in only three catalytic steps from commercially available building blocks is reported. This approach involves a diastereoselective diboration of alkenyl cyclopropyl methanol derivatives followed by a regioselective exergonic ring fragmentation. The starting materials can be prepared enantiomerically enriched and all substituents can be interconverted, therefore, this strategy allows a large variety of diversely functionalized allylboronic esters possessing distant tetrasubstituted stereocenters with high diastereoselectivity.

AbstractAbstract
[en] The extinguishants currently available for putting out magnesium alloy fires work by covering the burning fuel and excluding both the oxygen and nitrogen from the reaction zone. It has been reported that boron trifluoride and trimethoxi-and tributoxi-boroxine may act in a more specific chemical way on the combustion reactions. In this report an investigation into the effectiveness of these compounds on magnesium alloy fires is described. (author)

AbstractAbstract
[en] A general synthetic method has been developed for the rapid and efficient production of a variety of boron-rich macromolecules suitable for conjugation with or inclusion in receptor-mediated delivery systems as well as other delivery systems. Preparation techniques have been developed to yield precisely ordered oligophosphates which are soluble, hydrophilic, may be homogeneous, and may be prepared with a variety of functional groups.
