Paragraph 0045, (2017/08/29)
The invention relates to a novel cyclic bicarbodiimide compound (I) and a preparation method of the novel cyclic bicarbodiimide compound. Compared with monocarbodiimide, the novel cyclic bicarbodiimide compound has a higher molecular weight and a higher melting point; the disadvantage that the monocarbodiimide is easily transferred outward from compounds including polyester, polyurethane and like at high temperature is overcome; the anti-hydrolytic property of a material is improved; meanwhile, the defects that an existing bicarbodiimide compound is easily irregularly curled, easily forms a rubber state at room temperature and is not easy to crystallize and purify are overcome; the anti-hydrolytic effect is good and the bicarbodiimide compound has a good anti-hydrolytic property; the service life of a polyester material is improved; the bicarbodiimide compound can be used as an anti-hydrolytic stabilizer and is used for polyurethane and polyester elastomers, and especially can be used for photovoltaic industry, biodegradable materials and the like. The formula (I) is shown in the description.

A new polymer-anchored Cu(II) complex has been synthesized and characterized. The catalytic performance of the complex has been tested for the oxidation of sulfides and in oxidative bromination reaction with hydrogen peroxide as the oxidant. Sulfides have been selectively oxidized to the corresponding sulfoxides in excellent yields and in the presence of KBr as the bromine source, organic substrates have been selectively converted to mono bromo substituted compounds using polymer-anchored Cu(II) catalyst. This catalyst showed excellent catalytic activity, high selectivity, and recyclability. The polymer-anchored Cu(II) catalyst could be easily recovered by filtration and reused more than five times without appreciable loss of its initial activity.
