SYNTHESIS OF DIALKOXY-AMINO-DISUBSTITUTED AND ALKOXY-AMINO-DISUBSTITUTED DERIVATIVES OF B12H122-

Dichloromethoxymethane reacts with the sodium salt of closo-dodecahydr ododecaborate Na2B12H12 to give disubstituted cluster, which readily d ecomposes when treated with various reagents. This cluster reacts with water, forming the previously described 1,7-B12H10(OH)(2)(2-), reacti on with alcohols results in a novel 1,7-dialkoxy derivative, whereas i nteraction with morpholine in acetone solution affords the novel anion , 1-O-I-Pr-i-7-O(CH2CH2)N-B12H102-. All of these derivatives were isol ated as cesium salts and characterized by one- and two-dimensional NMR techniques.
