Reactivity of 1-Isothiocyanato Six Membered Silatrane towards Transition Metal Carbonyls

Abstract

This manuscript deal with the reaction of the 1-isothiocyanato six membered silatrane with different transition metal carbonyls. The adducts 1, 2, 3, 4 and 5 so formed were characterized by elemental analysis, infrared spectroscopy, 1 H, 13 C, 29 Si NMR spectroscopy. η 1 -S bonding pattern was observed amongst the various coordination modes of the isothiocyanato group. KEYWORDS: 1-Isothiocyanato six membered silatrane, Metal carbonyl, η 1 -S bonding I. III. SYNTHESIS Reaction of 1-Isothiocyanato six membered silatrane with Mo(CO) 4 (CH 3 CN) 2 (1)To the pale yellow colored solution of Mo(CO) 4 (CH 3 CN) 2 (1.40 g, 4.30 mmol) and 1,2-dichloroethane, taken in two necked round bottomed flask, solution of 1-isothiocyanato six membered silatrane (4.30 g, 8.60 mmol) was added.Contents were heated at 80 °C for 2 h in a constant temperature oil bath. Reaction mixture was allowed to attain room temperature and the solvent was removed under reduced pressure. Light brown mass was left behind was stirred in solvent ether for 15 min, filtered and dried.
