Abstract: Alkylcarbamoylborane cyclic dimers are synthesized through reactions of alkylcarbamoylborane adducts of amines. The inventive dimers have utility as reactants in the direct synthesis of alkylcarbamoylborane adducts of primary and secondary amines. Alkylcarbamoylborane adducts of primary and secondary amines and certain of the inventive dimers have biological activity as anti-tumor, hypocholesteremic, and anti-inflammatory agents. The cyclic dimers of this invention have the formula [BHRC(O)NHR'].sub.2, examples of which include:[BH.sub.2 C(O)NHC.sub.2 H.sub.5 ].sub.2[BH.sub.2 C(O)NHCH.sub.3 ].sub.2[BH.sub.2 C(O)NHCH.sub.2 CH.sub.2 CH.sub.3 ].sub.2[BH.sub.2 C(O)NHCH.sub.2 CH.dbd.CH.sub.2 ].sub.2.[BH.sub.2 C(O)NHC(CH.sub.3 ].sub.2.[BH(CH(CH.sub.3)CH.sub.2 CH.sub.3)C(O)NHCH.sub.2 CH.sub.3 ].sub.2.

Abstract: The present invention relates to novel organocyanohydroborate compounds which may be employed as reducing agents. For example, organocyanohydroborates having the following general formula are contemplated:M.sup.+ BH.sub.3 CR.sub.1 R.sub.2 CN.sup.-In this formula, R.sub.1 and R.sub.2 may be, for example, H, CH.sub.3, or C.sub.6 H.sub.5, or may be represented jointly, for example by C.sub.5 H.sub.10, while M.sup.+ is a cation which is capable of forming a salt. The organocyanohydroborate compounds of the present invention include a --CR.sub.1 R.sub.2 -- moiety between the BH.sub.3 moiety and CN moiety to provide a new class of hydroborate reducing agents.
