, p. 2714 - 2721 (2007/10/02)
Preparatory to the synthesis of catalysts, methods have been developed for the synthesis of macrocyclic ligands for transition metals which contain besides four endocyclic donor groups (-As(Ph)-, -S-) a variable side chain with a terminal halogen function

By application of the dilution principle 8 macrocycles (12-, 14-, 16-, 24-, and 28-ring, 5a, b, 7, 9a, b, 10a, b, 11b; yields 43 - 2percent) containing As and S as heteroatoms and 2 macrocycles (14- and 28-ring, 12a, b; yields 43percent, 7percent) containing As, S, and O as heteroatoms have been synthesized.The new smaller heterocycles 2-phenyl-1,2-thiarsolane (14a; max. 66percent) and 5-phenyl-1,5-thiarsocane (11a; 30percent) were formed as by-products.

, p. 5035 - 5038 (2007/10/02)
The synthesis of five eight-electron-ligands,two six-electronligands and one four-electron-ligand for transition metals is described.These heterocycles contain in each case arsenic and sulfur as heteroatoms, and additionally oxygen in one case.
