W. Clegg et al., A NOVEL, INTERNALLY-SOLVATED PHOSPHINOMETHANIDE - CRYSTAL-STRUCTURE OF LI[C(SIME3)(2)(P(C6H4CH2NME2-2)(2))], Chemical communications, (10), 1998, pp. 1129-1130
Metallation of P{CH(SiMe3)(2)}(C6H4CH2NMe2-2)(2) with (BuLi)-Li-n yiel
ds a novel lithium phosphinomethanide in which the ligand exhibits an
unprecedented tridentate PN2 coordination mode and in which there are
no short contacts between lithium and the planar carbanion centre.
