Metal-organo compounds with sterical-ly exposed metal-metal bonds,and a method for their production
Abstract
Abstract METAL-ORGANO COMPLEX CHARACTERIZED AS HAVING AT LEAST ONE STERICALLY EXPOSED METAL-METAL BOND, AND HAVING THE STRUCTURE: (R)N-M==M''(-R)N WHERE R REPRESENTS A LIGAND WHICH MAY CONTAIN ONE OR MORE ATOMS OF CARBON, HYDROGEN, OXYGEN, NITROGEN, SULFUR OR PHOSPHORUS; N IS AN INTEGER OF FROM 1 TO 3; M AND M'' EACH REPRESENT THE SAME OR A DIFFERENT TRANSITION METAL; AND THE SYMBOL == REPRESENTS AT LEAST ONE STERICALLY EXPOSED METAL-METAL BOND. THE PREPARATIVE METHOD INVOLVES THE LOW TEMPERATURE REACTION BETWEEN AN ALKALI METAL NAPHTHALENE IN AN ETHEREAL SOLVENT, WITH THE DIHALOGENIDE OF AT LEAST ONE METALORGANIC SPECIES. THE REACTION MIXTURE IS ALLOWED TO SLOWLY WARM TO AMBIENT TEMPERATURES, THE SOLVENT IS EVAPORATED, AND THE NAPHTHALENE SUBLIMED AT TEMPERATURES BELOW 40*C. THE REMAINING CRUDE PRODUCT IS EXTRACTED WITH AN ORGANIC SOLVENT, THE EXTRACT IS SEPARATED FROM THE INSOLUBLE PORTION, AND THE PRODUCT RECOVERED BY EVAPORATIGN THE SOLVENT. THE METAL-ORGANO COMPLEX HAS UTILITY AS AN ABSORBETN OF NITROGEN WHEN PRESENT AS A CONTAMINAT IN ARGON.
