Synthesis of New BF2-Chelate Compounds

4-pyrimidylideneacetonitrile derivatives containing $BF_2$-chelate have been synthesized from H-chelates of 4-pyrimidylideneacetonitrile derivatives and boron trifluoride diethyl etherate. These H-chelates were prepared by the electrophilic substitution of 2-cyanomethylpyridine derivatives with electrophiles such as 4,6-dichloropyrimidine, 4,6-dichloro-2-methylpyrimidine, 4,6-dichloro-2-heptadecylpyrimidine, 4,6-dichloro-2-phenylpyrimidine, 4,6-dichloro-5-phenylpyrimidine and 4,6-dichloro-2,5-diphenylpyrimidine. Structures of the target molecules were identified by spectra methods.

새로운 BF2-Chelate 화합물들의 합성

$BF_2$-chelate 형태의 4-pyrimidylideneacetonitrile 유도체들은 4-pyrimidylideneacetonitrile 유도체들의 H-chelate 화합물들과 boron trifluoride diethyl etherate를 반응시켜 얻을 수 있었다. 또 이들 H-chelate 화합물들은 2-cyanomethylpyridine 유도체들에 여러가지 친전자체들 즉 4,6-dichloropyrimidine, 4,6-dichloro-2-methylpyrimidine, 4,6-dichloro-2-heptadecylpyrimidine, 4,6-dichloro-2-phenylpyrimidine, 4,6-dichloro-5-phenylpyrimidine 그리고 4,6-dichloro-2,5-diphenylpyrimidine을 친전자성 치환반응시켜 만들었다. 화합물에 대한 구조는 분광학적인 방법으로 분석하였다.
