Abstract

Preparative procedure for obtaining the secondary and tertiary amines of o-carborane [1,2-dicarbadodecaborane(12)] series by lithium aluminum hydride reduction of their acyl derivatives has been worked out.N-Nitroso and N-nitro derivatives of the secondary amines of o-carborane series were obtained. Cleavage of 3-(acetylnitrosoamino)-o-carboranes was suggested to involve formation of 3-o-carboranyl radical.An internal salt of 3-trimethylammonium 1,2-dicarbaundecaborane(13) was prepared which could be sublimed in vacuo.The earlier unknown o-carboran-3-yl isocyanates were synthesized and some of their properties investigated.Carborane analogues of the Schiff's bases were prepared from 3-amino-ocarboranes and aldehydes and their properties investigated.o-Carboran-3-yl isonitriles were synthesized from 3-amino-o-carboranes, and their possible isomerization to o-carboran-3-ylnitriles was discovered.
