Treatment of osmacyclopentadiene derivatives 1 with Ph or iso-Pr isothiocyanate gave the fused five and six-membered osmacycles 2–5 by a formal [4+2] cyclization. The facile protonation of the newly generated exocyclic imine in complexes 2–5 afforded conjugation-extended osmacycle derivatives 6–9. Compounds 2–9 each contain two main-group heteroatoms (N and S) in the fused six-membered ring located at the ortho (for S) and para (for N) positions relative to the osmium center; these species can be regarded as rare osma-1,3-thiazine derivatives and represent the first fused metallathiazine derivatives In contrast to the non-planar organic 6H-1,3-thiazine, nearly coplanar metallathiazines 8 and 9 can be achieved by tuning the groups on the two nitrogen atoms. These unique metal-bridged osma-1,3-thiazine derivatives exhibit remarkable stabilities, broad spectral absorptions spanning the visible spectra, and considerable photothermal properties, which suggests their potential applications in material science. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8SDS of cas: 2253-73-8).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.SDS of cas: 2253-73-8
