The reaction of the heterocycles CH3NSi(CH3)2C(R3)=C(C2H5)B(C2H5) 3 = CH3: A; R3 = C(CH3)=CH2: B> with the prim.-aminohydroxyalkanes H2N-R-OH 3-: 3; -4-: 4>, the prim.-aminophenols H2NC6H4OH , and the sec.-aminohydroxyalkanes HN(CH3)-R-OH 2-: 7; (R,S)-CH(CH3)CH(C6H5)-: 8; (S,S)-CH(CH3)CH(C6H5)-: 9> leads to elimination of CH3NH2 with formation of the compounds 11a, b, 12-15 and 17-19 as monocyclic aminoboranes R1N-R-O-Si(CH3)2C(R3)=C(C2H5)B(C2H5) (R1 = H,CH3; R3 = CH3) and iso-11a, b iso-12-iso-15 as bicyclic amine-boranes R1NSi(CH3)2C(R3)=C(C2H5)B(C2H5)OR.The isomeric compounds 11a and iso-11a are transformed into one another by crystallisation and by dissolution or distillation, resp.A reacts with the tert.-aminoethanol (CH3)2NCH2CH2OH (10) to give the acyclic compound (CH3)2N(CH2)2OSi(CH3)2C(CH3)=C(C2H5)B(C2H5)O(CH2)2N(CH3)2 (20).Further reactions of A with the NH2 compounds HN(CH3)2NH2 (21), CH3C(O)NH2, and NCNH2 to the compounds E, 23, and 24, resp., are described. - The compounds C2H5BN(R1)-R-O (f1) and cis-HC(C2H5)=C(CH3)Si(CH3)2ORNH2 (f2) are formed as side products by BC(vinyl)-fission.
