A series of 4,6,7,8-tetrahydro-2,5-（1H,3H）-quinolinediones was prepared from ethyl-2-cyanoacetate, aromatic aldehydes and 1,3-cyclohexanedione or 5,5-dimethyl-1,3-cyclohexanedione by two steps, the yields were moderate to excellent. This method is a new practical promising green strategy to synthesize tetrahydronquinolin-2,5-diones.

A novel and efficient method was developed for the liquid-phase synthesis of Nj,4-disubstitutedbenzodiazepine-2,5-diones with 2-chloro-5-nitrobenzoic acid as initiating material via 4 step reactions containing esterifieation, ＂Ulmn reaction＂, acylation, alkylation and cyclization. The reaction conditions were mild and the overall yields of the products ranged from 45% to 71%.

Polysubstituted cyclopropanes were efficiently prepared with poly（ethylene glycol）（PEG） as soluble support. The reaction of PEG-supported pyridinium ylide with arylidenemalononitrile（R=CN） or ethyl arylidenecyanoa-cetate（R=COOEt） in the presence of triethylamine（TEA） afforded PEG-supported cyclopropanecarboxylates, which were cleaved by 1% KCN/EtOH to obtain polysubstituted cyclopropanes with exclusive trans-selectivity and good yields.

期望理论为不确定性条件下决策的规范理论,然而"交换悖论"对之提出质疑。从经济学的效用理论的角度来看,由于金钱数不等于效用值,由于决策主体的效用满足边际效用递减规律,而"交换悖论"误将效用等同于金钱数了,因此交换悖论不是严格意义上的悖论。这样,"交换悖论"得以消解。

The adsorption of pollutants can not only promote the direct surface reaction,but also modify the catalyst itself to improve its photoelectric characteristics,which is rarely studied for water treatment with inorganic photocatalyst.A highly crystalline BiOBr(c-BiOBr)was synthesized by a two-step preparation *** to the calcination,the highly crystalline enhanced the interface interaction between pollutant and *** complex of organic pollutant and[Bi_(2)O_(2)]^(2+)could promote the active electron transfer from the adsorbed pollutant to c-BiOBr for the direct pollutant degradation by holes(h^(+)).Moreover,the pollutant adsorption actually modified c-BiOBr and promoted more unpaired electrons,which would coupling with the photoexcitation to promote generate more O_(2)^(•-).The molecular modification effect derived from pollutant adsorption significantly improved the removal of *** work strongly deepens the understanding of the molecularmodification effect from the pollutant adsorption and develops a novel and efficient approach for water treatment.

企业与员工订立劳动合同的过程是一个联盟博弈或合作性博弈的过程:通过协议分割收益或预期收益。联盟的预期总收益为预期的劳动产量的市场实现减去员工的机会成本,预期总收益大于0为企业与员工能够进行讨价还价、形成联盟的条件。在这个博弈中,员工往往作出"空口声明",而企业则努力对员工这样的声明进行分辨。
