Methoxy(phenyldimethylsilyl)methyl-lithium provides a new formyl anion equivalent which affords α-hydroxyaldehydes via an oxidative desilylation procedure.
Synclinal and Anticlinal Isomers of the Iron Methoxycarbene Complex 5-C5Me5)Fe(CO)2(=CHOMe)>(1+); Access to Functional Compounds

The methoxymethyl complex (η5-C5Me5)Fe(CO)2(CH2OMe) (2) undergoes hydride abstraction with Ph3C(1+)PF6(1-) at -80 deg C and affords the secondary methoxycarbene complex 5-C5Me5)Fe(CO)2(=CHOMe)>(1+)PF6(1-) (1) as a mixture of two geometric isomers of which the syn form isomerizes upon warming; complex (1) adds PPh3 yielding quantitatively 5-C5Me5)Fe(CO)2(CHOMePPh3)>(1+)PF6(1-) (3), and converts Me2PhSiH into Me2PhSiCH2OMe (4), giving in the presence of the appropriate alkenes, the alkene complexes 5-C5Me5)Fe(CO)2(CH2=CHR)>(1+)PF6(1-) (5).
