Abstract
Fe(CO)5와 알킨일리튬의 반응에서 생성된 아실 음이온 착물을 CH3CH2OSO2F로 처리하는 방법으로 5종의 철 알킨일카르벤 착물 유도체(1)들을 합성하였다. [R-C≡C-C(OCH2CH3)]Fe(CO)4(R = n-프로필, 시클로헥실, t-부틸, 트리메틸실릴, 페닐). 트리메틸시릴기가 치환된 유도체(1d)와 8종의 열린 고리 1,3-디엔과의 반응에서 η3-비닐카르벤 착물 유도체(2)를 주생성물로 얻었다.

Five (alkynylethoxymethylene)Fe(CO)4 complexes (1) are prepared through the reaction of Fe(CO)5 with alkynyllithium (R = n-Pr, cyclohexyl, t-Bu, trimethylsilyl, Ph) and subsequent O-ethylation of the resulting acyl anion complexes with ethyl fluorosulfonate. In the reactions of trimethylsilyl-substituted alkynylcarbene complex (1d) with 8 open-chain 1,3-dienes, (η3-vinylcarbene)Fe(CO)3 complexes (2) are obtained as major products.
