The hallmark of nucleophilic phosphine catalysis is the initial nucleophilic addition of a
phosphine to an electrophilic starting material, producing a reactive zwitterionic …

Allenes are the simplest class of cumulenes, with two contiguous C C bonds, and show
unique physical and chemical properties. These features make allenes particularly attractive …

Allene–Verbindungen mit zwei benachbarten C C‐Bindungen–bilden die einfachste
Klasse unter den Cumulenen. Sie verfügen über außergewöhnliche physikalische und …

A phosphine-catalyzed (3+ 2)/(2+ 3) sequential annulation involving a triple nucleophilic
addition reaction of γ-vinyl allenoates was successfully developed. The reaction provided …

Organophosphorus Chemistry provides a comprehensive annual review of the literature.
Coverage includes phosphines and their chalcogenides, phosphonium salts, low …

A highly selective phosphine-catalyzed β-addition of α-fluoro β-dicarbonyl compounds to
allenoates has been developed. Both α-fluoro β-diketones and α-fluoro β-keto esters prove …

This chapter covers the literature published during 2013 relating to the above area, apart
from a few papers from 2012 in less accessible journals which came to light in Chemical …

Allenes have a unique structural feature characterized by having two cumulated double
bonds. The inherent instability associated with these 1, 2-dienes has been widely exploited …

We have developed a phosphine‐catalyzed (4+ 1) annulative rearrangement for the
preparation of 3‐pyrrolines from allenylic carbamates via phosphonium diene intermediates …

Abstract α, β-Unsaturated γ-amino esters can be synthesized efficiently and
stereoselectively through phosphine-catalyzed γ-umpolung additions of sulfonamides to γ …
