摘要

Borylation of potassium pentadienide with BCl (NR2) z and subsequent alcoholysis produce 2, 4-pentadienylboranes CsH7B (NR2) 2 (4a-c: R= Me, Et, Pri), CsH7B (OR) z (4e, f: R= Et, But), and CsH7B (OCR2) 2 with 1, 3, 2-dioxaborolane rings (4g, h: R= H, Me) as mixtures of E and 2 isomers. Metahtion of 4a, b in THF by lithium dialkylamides LiNR2 (R= Me, Et, Pi) in the presence of TMEDA results (i) in a nonproductive deborylation via primary attack at the ...
