Aj. Ashe et Pm. Savla, THE PREPARATION OF (Z)-2-LITHIO-ORTHO-STYRYLLITHIUM VIA AN ORTHO-DIRECTED LITHIATION, Journal of organometallic chemistry, 461(1-2), 1993, pp. 1-3
Lithiation of (Z)-2-lithiostyrene with t-butyllithium/TMEDA pentane le
d directly to (Z)-2-lithio-ortho-styryllithium. Subsequent treatment o
f this dilithio compound with difunctional electrophiles allowed the p
reparation of a variety of benzo[b]heteroles.
