Solvent-dependent lithium bridging in allenyl-propargyllithium reagents
Reich, Hans J.,Thompson, Jennifer L.
, p. 783 - 786 (2000)
(figure presented) The solution structures of two allenyl-propargyllithium reagents (6-Li and 7-Li) which give 13C NMR chemical shifts intermediate between those expected for the allenyl and propargyl isomers have been studied by the Saunders i
Solution structure and stereochemistry of alkyl- and silyl-substituted allenyl-propargyllithium reagents

Analysis of 13C chemical shifts and Li-C couplings showed that allenyllithium (5A-Li) was a mixture of monomer and dimer in THF, both with an allenyl structure. Similarly, the metalation products of 2-butyne (6A-Li), 4-methylpentyne (9A-Li), an
The Regiochemistry and Stereochemistry of the Hydroboration of Allylsilanes
Fleming, Ian,Lawrence, Nicholas J.
, p. 3309 - 3326 (2007/10/02)
The hydroboration of a wide range of allylsilanes 3 and 5-21 is found to be generally regioselective for attachment of the boron to C-3 and hydrogen to C-2 of the allyl unit, and to be generally stereoselective in the sense 1, with attachment of the boron
