资源简介：
The (η3-disilaallyl)lithium derivative 5 was synthesized by the reaction of the disilenyllithium species (tBu2MeSi)2SiSi(SiMetBu2)Li (1) with tris(3,5-di-tert-butylphenyl)acetaldehyde. All data, including X-ray analysis and NMR spectra, show that 5 has a π-allyl-type structure, with an interaction between the Li+ ion and the SiC π-electrons of the silene moiety in both the crystal structure and in toluene solution but no such interaction in polar THF solvent.
