A facile synthesis of two gold(I) complexes with 1,2-benzenedithiolate ligand and two different bidentate phosphines are described. A detailed sequence of NMR experiments is suggested to determine the structure of the compounds.

Debates whether a text claiming to have scientific value is using seduction irresponsibly at the expense of the truth, and discusses who is the subject and who is the object of such seduction. It argues that, rather than being an assault against scientific ethics, seduction is a necessary premise for a sensible conversation to take place. (GR)

Organic v inorganic dichotomy in chemistry has begun to disappear while a new formal research discipline, bioinorganic chemistry, is emerging. The field has been developed with the realization that a third of all proteins and bioenzymes contain an inorganic element such as a metal critical to their chemical nature. (Author/RE)

Analyzes instructional theory requirements and suggests that structural learning theories meet these requirements. Essentials of such theories are illustrated in the context of designing an instructional unit on subtraction. Structural learning theories are then described more generally and contrasted with cognitive theories. Implications for…

Questions the use of the Reactivity Selectivity Principle (RSP) by teachers and authors of texts in discussing organic reaction mechanisms. Provides some applications and failures of the use of the RSP, reviews some quantitative aspects of the RSP, and discusses some of the rationalization of the RSP failures. (TW)
