Abstract

The reactions between h 5-CpFe(CO) 2R (R = CH 2CHCH 2; CH 2CMe=CH 2; CH 2CHCHMe; CH 2CHCMe 2) and stannous chloride in tetrahydrofuran afford the insertion products h 5-CpFe(CO) 2SnCl 2R. When treated with stannous chloride in methanol or with excess stannous chloride in tetrahydrofuran, h 5-CpFe(CO) 2CH 2CMeCH 2 affords primarily h 5-CpFe(CO) 2SnCl 3. The allenyl, 2-butynyl or cationic isobutylene complexes (R = CHCCH 2; CH 2 CCMe; CH 2CMe + 2) yield only h 5-CpFe(CO) 2SnCl 3. Stannous iodide reacts with h 5-CpFe(CO) 2CH 2CHCH 2 in benzene to form h 5-CpFe(CO) 2I. Plumbous chloride in methanol fails to react with the above complexes.
