The synthesis of metal organic compounds of calcium, strontium and barium by ammonia gas-saturated ethereal solvents

Abstract

The activation of the alkaline earth metals Ca, Sr and Ba in ammonia gas-saturated ethereal solvents at room temperature leads to rapid reaction with hexamethyldisilazide, pentamethylcyclopentadiene, triphenylsilanol, phenylacetylene, and triphenylmethane to yield the corresponding silamide, metallocene, siloxide, phenylacetylide and triphenylmethyl derivatives; ESR spectroscopic studies of the reaction system have detected the presence of solvated electrons.
