Peer reviewedCerrada, Elena; Laguna, Mariano – Journal of Chemical Education, 2005
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.

Scandura, Joseph M. – Journal of Computer-Based Instruction, 1984
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…

Peer reviewedBuncel, Erwin; Wilson, Harold – Journal of Chemical Education, 1987
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)
