Abstract

Reaction of [РtМе3(Ме2СО)3]BF4 (1) with 3-О-acetyl-1,2;5,6-di-О-isopropylidene-α-D-glucofuranose in acetone affords [PtMe3L]BF4 (2) (L = 3-O-aсеtyl-1,2-О-isoрropylidene-α-D-glucofurаnоse). In wet methylene chloride the complex 2 transforms to [РtМe3L(Н2O)]BF4·Н2O (3).

Complex 3 was characterized by microanalysis and NMR spectroscopy (1Н, 13С, 195Рt). The X-ray structure analysis (monoclinic, Р21, a = 10.529(3) Å, b = 7.322(2) Å, c = 14.668(4) Å, Z = 2) reveals that 3-О-acetyl-1,2-О-isopropylidene-α-D-glucofuranose acts as a neutral bidentate ligand which is coordinated via two hydroxyl groups (k2O5,6 coordination). The five-membered 1,3,2-diохaрlаtina rings exhibit an envelope conformation. The coordination sphere of platinum is completed by Н2O ligand.
