Protonation of a lanthanum phosphide-alkyl occurs at the P–La not the C–La bond: isolation of a cationic lanthanum alkyl complex
Abstract
Protonation of the heteroleptic, cyclometalated lanthanum phosphide complex [{(Me3Si)2CH}(C6H4-2-CH2NMe2)P]La(THF)[P(C6H4-2-CH2NMe2){CH(SiMe3)(SiMe2CH2)}] with [Et3NH][BPh4] yields the cationic alkyllanthanum complex [(THF)4La[P(C6H4-2-CH2NMe2){CH(SiMe3)(SiMe2CH2)}]][BPh4].
