Synthesis of dialkoxy- and alkoxy-amino-disubstituted derivatives of B12H122−
Dichloromethoxymethane reacts with the sodium salt ofcloso-dodecahydrododecaborate Na2B12H12 to give disubstituted cluster, which readily decomposes when treated with various reagents. This cluster reacts with water, forming the previously described 1,7-B12H10(OH)22−reaction with alcohols results in a novel 1,7-dialkoxy derivative, whereas interaction with morpholine in acetone solution affords the novel anion, 1-O-I-Pri-7-O(CH2CH2)N-B12H102−. All of these derivatives were isolated as cesium salts and characterized by one- and two-dimensional NMR techniques.
