Erratum: Synthesis of functional phosphines with ortho‐substituted aryl groups: 2‐RC₆H₄PH₂ and 2‐RC₆H₄P(SiMe₃)₂ (R = i‐Pr‐ or t‐Bu)

Abstract

The synthesis and characterization of 2‐i‐PrC6H4PCl2 (3), 2‐t‐BuC6H4PCl2 (4), 2‐i‐PrC6H4PH2 (5), 2‐t‐BuC6H4PH2 (6), 2‐i‐PrC6H4P(SiMe3)2 (7), and 2‐t‐BuC6H4P(SiMe3)2 (8) are described. © 2010 Wiley Periodicals, Inc.

Enantiomerically Pure Phosphaalkene–Oxazolines (PhAk‐Ox): Synthesis, Scope and Copolymerization with Styrene

“…Although the stability of a mono‐ ortho ‐aryl phosphaalkene was uncertain, we moved ahead and attempted to prepare new PhAk‐Ox compounds from 2‐ i PrC 6 H 4 P(SiMe 3 ) 2 33 and 2‐ t BuC 6 H 4 P(SiMe 3 ) 2 33. Remarkably, treatment of ketone 5 with in situ generated 2‐ i PrC 6 H 4 P(SiMe 3 )Li afforded phosphaalkene 1 c (85 %) in analytical purity after distillation.…”

“…Styrene was purchased from Aldrich and distilled from CaH 2 prior to use. L ‐Valinol,27 oxazoline 4 ,26 MesP(SiMe 3 ) 2 ,19 2,4,6‐( i Pr) 3 C 6 H 2 P(SiMe 3 ) 2 ,37 2‐ i PrC 6 H 4 P(SiMe 3 ) 2 ,33 and 2‐ t BuC 6 H 4 P(SiMe 3 ) 2 33 were prepared according to literature procedures. 1 H, 31 P{ 1 H}, and 13 C{ 1 H} NMR spectra were recorded at 25 °C on Bruker Avance 300 or 400 MHz spectrometers.…”
