Phosphole oxide derivatives, synthesis

A general method of synthesis of phosphole derivatives is illustrated by the preparation of l-phenoxy-3,4-diphenylphosphole 1-oxide (112) by a bromination-debromination sequence as shown. ... [Pg.27]

N.Z. Kiss, A. Simon, L. Drahos, K. Huben, S. Jankovski, G. Keglevich, Synthesis of l-amino-2,5-dihydro-lH-phosphole 1-oxides and their N-phosphinoyl derivatives, bis(2,5-dihydro-lH-phoshol-l-yl)amine P,P -dioxides, Synthesis 45 (2013) 199-204. [Pg.569]

A convenient and efficient synthesis of 4-halo-2,5-dihydro-l,2-oxa-phosphole 2-oxides (254) through CuX2-mediated direct halocyclisation of diethyl 1,2-allenylphosphonates (253) has been described by Ma and Xin. Further Suzuki cross-coupling of the resultant chloro derivatives (254) with phenylboronic acid, has been also established (Scheme 90). ot-Amino allenephosphonates (258) have been easily prepared in two steps from protected amines (255), 3-bromopropargyl alcohols (257) and chlorophosphites. In the first step, a copper (II) catalysed coupling reaction of unprotected 1-bromopropargyl alcohols (256) and amines (256)... [Pg.290]
