Abstract: Six organophosphine/phosphite stabilized N-silver(I) succinimide complexes of the type L n ·AgNC4H4O2 (L=PPh3; n =1, 2a; n =2, 2b; n =3, 2c; L=P(OEt)3; n =1, 2d; n =2, 2e; n =3, 2f) have been prepared by reacting [AgNC4H4O2], which can be synthesized from succinimide and excessive Ag2O in boiling water, with triphenylphosphine or triethylphosphite in dichloromethane under a nitrogen atmosphere. These complexes were obtained in high yields and characterized by elemental analysis, 1H, 13C{H} NMR, IR spectroscopy and thermal analysis (TG and DSC). The molecular structure of 2c has been determined by X-ray single crystal analysis, in which the silver atom is in a distorted tetrahedral geometry. [Copyright &y& Elsevier]

Objective: To identify related factors of job burnout in Shanghai employees., Methods: Four hundred fifty-six employees in Shanghai were investigated in this study. Self-administered questionnaires were used to assess job burnout and job stress, based on Maslach Burnout Inventory and the Job Demand-Control model as well as Effort-Reward Imbalance Model. Hierarchical linear regression was employed to analyze the relationship of job burnout to personal characteristics and job stress., Results: The indexes of three dimensions of job burnout were emotional exhaustion 19.70 +/- 8.92, depersonalization 11.95 +/- 4.45 and reduced personal accomplishment 28.10 +/- 10.08. Job stress was found to be affected differently in three dimensions of job burnout. Job demand, effort and over-commitment had positive impact on emotional exhaustion. Job control had a negative association with emotional exhaustion. There were significant relationship between depersonalization and age, sex and education of employees. Job control, reward and over-commitment affected the index of depersonalization. Education level and social support increased personal accomplishment index., Conclusion: It is necessary to reduce job stress and care about personal characteristics in preventing job burnout.
