A mixture of 3 mol of Me6Si2 and 1 mol of MeLi in the presence of P(O)(NMe2)3 produced Me3SiLi as the initial product. This then deprotonated excess Me6Si2 and started an unprecedented transformation leading to (Me3Si)2(SiMe2H)CLi (3), whose quench by [(η5-C5H5)Fe(CO)2PPh 3+] produced {η4-exo-[(Me3Si)2C-(SiMe 2H)]C5H5}Fe(CO)2(PPh3) (2e). In the literature the reaction of Me6Si2 and MeLi gives Me3SiLi and/or Me3SiSiMe2Li (4). The lithium compound 3 is the major product when a previously unnoticed deprotonation pathway is enhanced by use of an excess of Me6Si2 and a longer reaction time.
