Dess-Martin periodinane oxidizes very rapidly 2-pyridylseleno derivatives RR′CHCH2SePy in CHCl3 or CH2Cl2 and more chemoselectively than mCPBA. Tetravalent selenanes, RR′CHCH2Se(OAc)2Py, se

The present invention relates to a single source metalloorganic precursor compound of the formula: wherein M is selected form the Group 14 elements of Germanium, Tin or Lead; A and R are independently selected from: amide, alkyl having from 1 to 20 carbon atoms, aryl, substituted aryl, or -Q'-2-NR'Ln (n=1-4) wherein L is selected from nothing or a Lewis base ligand; Q and Q' are each independently selected from Group VIa elements of sulfur, selenium, or tellurium; and 2-NR and 2-NR' are each independently selected from N-heterocyclic aryl or its derivatives. Methods of producing these compounds are also disclosed. These precursor materials provide in a single compound the binary, tertiary, or quaternary metals in a ratio to each other that is controllable by a judicious choice of metal atoms and organic substituents. The metal alloys are useful in a variety for electronic applications, particularly in semiconductors and solar energy.
