Among the tested iodo derivatives, compounds 3b and 9a possess interesting activities against the aforesaid fungal strains in several cases similar to that of benodanil I taken as reference drug.

Hydroboration of these imines with catecholborane (HBcat, cat = 1,2-O2C6H4) at room temperature gives, upon aqueous workup, the corresponding borylamines. An X-ray diffraction study was carried out on imine 1h derived from 9-anthraldehyde and 3-H2NC6H4Bpin. Crystals of1h were triclinic, a = 9.6793(4) Å, b = 10.7397(4) Å, c = 11.5353(4) Å, α = 105.1890(10)o, β = 97.3030(10)o, γ = 102.1480(10)o, Z = 2 with space group P[Formula: see text] and crystals of N-[3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-4-methoxybenzylamine 2c were orthorhombic, a = 8.6612(4) Å, b = 10.3794(4) Å, c = 20.6033(9) Å, Z = 4 with space group P212121. Amines have been tested for their antifungal properties against Aspergillus niger and Aspergillus flavus.Key words: benzylamines, boronate esters, aminoboron, hydroboration, antifungal.

Addition of 2-formylphenylboronic acid to the thiosemicarbazides gave the corresponding cyclic 2,3,1-benzodiazaborines. All new compounds have been investigated for potential antifungal activity.

All iminopyridine complexes were characterized by physicochemical and spectroscopic methods. The molecular structures of two complexes, 2a and 2b, were determined by single crystal X-ray diffraction studies. All complexes were tested for their potential antifungal and antibacterial activities.

All compounds were characterized fully using multinuclear NMR spectroscopy, FT-IR spectroscopy and by elemental analyses. A single crystal X-ray diffraction was carried out on triethylmethylammonium 4-nitro[1,2-benzenediolato(2-)-O,O′]borate (5). All new compounds were tested for potential fungicidal activity.

It is then argued that oil disruptions of the 1970s, new gas discoveries and the “steel for gas” deals with the Soviet Union were decisive for the evolution of the current gas infrastructure. The parts of the chapter that trace the developments of the EU gas markets after the Soviet breakup and Eastern enlargement show that the 2006 and 2009 gas interruptions to Ukraine have partially motivated new EU gas legislation, which Russia perceived as threatening to her economic interests.
