Ring expansion in dimetallacycle chemistry: preparation of a dimetallacyclopentanol from a dimetallacyclobutane
Abstract
Treatment of the dimetallacyclobutane complex [(OC)3Fe(µ-dppm){µ-C(CH2)CH2}Pt(PPh3)](dppm = Ph2PCH2PPh2) with an excess of LiBHEt3 followed by methanol quantitatively gave the dimetallacyclopentanol complex [(OC)2Fe(µ-dppm){µ-σ:η3-CH(OH)C(
CH2)CH2}Pt(PPh3)].
