  摘要：

  AbstractDimethylaminobis(trifluoromethyl)borane, (CF3)2BNMe2 (A), reacts with Cl(CH2)3CN to yield [Cl(CH2)2CH(CN)](CF3)2B·NHMe2 (1) whereas Br(CH2)3CN and A combine in a 1:2 ratio to form [cyclo‐C3H4(CN)](CF3)2B·NHMe2 (2) and Br(CF3)2B·NHMe2. Br(CH2)nCN and A yield [Br(CH2)n‐1 CH‐(CN)](CF3)2B·NHMe2, n=4 (3), n=5 (4) and n=6 (5). Compound 2 and (NCCH2)CF3)2B·NHMe2 can be alkylated at nitrogen with CH3I/KOH in ether to yield [cyclo‐C3H4(CN)]‐(CF3)2B·NMe3 (6) and (NCCH2)(CF3)2B·NMe3 (7), respectively. treatment of 1 and 3 with hydroxide in ether gives the respective five‐ and six‐membered heterocycles (CF3)2 (8) and (9). Reduction of the nitrile group with (iBu)2Alh in CH2Cl2 at –50°C followed by hydrolysis furnishes the corresponding aldehydes (OCHCH2) (CF3)2B·NMe3 (10), [cyclo‐C3H4(CHO)](CF3)2B·NMe3 (11) and (12). The structure of 2 was determined by an X‐ray investigation.
