    • This application relates to the use of phosphonium-based ionic liquids as recyclable solvents for solution phase chemistry. The ionic liquids may be used, for example, as solvents for reactions involving Grignard reagents, hydridic reagents, metallic and non-metallic reducing agents, and strong bases, including nucleophilic carbenes and Wittig reagents. In one embodiment the invention may comprise homogeneous mixtures of strong bases/nucleophiles/reducing agents and tetrahydrocarbylphosphonium salt ionic liquids. The invention also relates to chemical processes that may proceed in either minimally flammable solvent, or a complete absence of flammable solvent, including systems containing strong reducing agents such as alkali and alkaline metals or metal and non-metal hydrides. Methods for generating anions and nucleophililic carbenes (imidazol-2-ylidenes) (and complexes derived from them) in phosphonium-based ionic liquids are also described. The invention demonstrates the feasibility of using phosphonium-based ionic liquids as a reliable reaction media for a wide variety of basic reagents. The problems associated with C-H activation in imidazolium-based ionic liquids by highly reactive bases are not observed for phosphonium-based ionic liquids.

    • The present invention provides a polymer of Formula (4) or (5) as manufactured by polymerizing alkylmethacrylate of the formula (1) or its salt with 2-metacroxyethyl triammonium chloride of Formula (2) or vinyl monomer of phosphonium salt of the formula (3), and further provides a photochromic polymer matrix manufactured by blending the said polymer as the supporter with a known photochromic organic compound. Further, the present invention enables a glass or a mirror, of which the transmittance and/or the reflectance can be adjusted, to be manufactured by coating it with the said photochromic polymer matrix in a given thickness.
      In the case of the glass manufactured by using the matrix of the present invention, it can be used in the field requiring adjustment the transmittance of light depending upon a weather condition, including a building or a car glass, a sunroof and the like. In the case of the mirror manufactured so, it can be applied to a rear-view mirror and a side view mirror for a vehicle and the like.
