Abstract
Tricarbonyl(2-methyl-1-phenylpentadienyl)iron(+1) hexafluorophosphate 양이온이 hexafluorophosphoric acid를 사용한 tricarbonyl(4-methyl-5-hexadien-1-ol)iron의 양성자 첨가반응에 의해 얻어졌다. 그 양이온과 H2O, dimethyl cuprate, diphenylacetylenyl cuprate, 그리고 cyclohexanone의 enolate와의 반응은 그것들에 대응하는 (η4-1,3-diene)Fe(CO)3를 형성시켰다. 친핵체의 공격에 있어서의 위치 선택성은 주로 입체효과의 결과인 것으로 보인다.

Tricarbonyl(2-methyl-1-phenylpentadienyl)iron(+1) hexafluorophosphate cation was prepared by the protonation of tricarbonyl(4-methyl-5-hexadien-1-ol)iron wit hexafluorophosphoric acid. Reaction of the cation with water, dimethyl cuprate, diphenylacetylenyl cuprate, and enolate of cyclohexanone gave the corresponding (η4-1,3-diene)Fe(CO)3. The regioselectivity for the nucleophilic attack appears to the predominantly the result of steric effect.
