Alkali metal cation π-interactions in metalated and nonmetalated acetylenes: π-Bonded lithiums in the X-ray crystal structures of [Li-C≡C-SiMe2-C6H4-OMe]6 and [Li-O-CMe2-C≡C-H]6 and computa

The X-ray crystal structure of [Li-C≡C-SiMe2-C6H4-OMe]6 (14)6 features nearly symmetric π-interactions between the lithium ions and the acetylide anions (Li1-C(β) = 2.353(9) A?, Li1/s

5-Exo cyclizations of primary and secondary radicals with acylsilanes successfully give cyclopentyl silyl ethers. The corresponding 6-exo cyclizations are sensitive to changes of the size of silyl groups. Secondary radicals undergo 6-exo cyclizations with

Several diarylsilanes 5,9 and 11 do not cleave with lithium in THF to give silyl-lithium reagents, in contrast to diphenyltetramethyldisilane 2, which is well known to give phenyldimethylsilyl-lithium.Trityldiphenylsilyl bromide 13 reacts with lithium to
