WebMar 23, 2007 · A series of sulfonium halides bearing allyl groups have been prepared and characterized. Anion metathesis with Li [Tf 2 N] and Ag [N (CN) 2] resulted in sulfonium-based ionic liquids which exhibit low viscosities at room temperature. The solid state structure of one of the halide salts was determined by single crystal X-ray diffraction. WebIn secondary analysis, two distinct subgroups were identified within the SDF group: one as long-term treatment (n=9) and one as interim treatment prior to general anesthesia (n=16). The long-term group was younger (mean=3.2 versus 3.7), had lower dmft (mean=4 versus 11.1), and had lower frequency of very high dental anxiety (0% versus 15%). ...
