Developing the Catalytic Applications of 1,3,2-Diazaphospholenes

The development of new catalytic methods for organic synthesis is a critical endeavour in order to obviate the economic and ecological drawbacks of stoichiometric organic synthesis. While catalysis can offer significant advantages in terms of atom-economy, ...

1,3,2‐Diazaphospholenes Catalyze the Conjugate Reduction of Substituted Acrylic Acids

Nicolai Cramer, John Henry Reed

The potent nucleophilicity and remarkably low basicity of 1,3,2- diazaphospholenes (DAPs) is exploited in a catalytic, metal-free 1,4-reduction of free ,-unsaturated carboxylic acids. Notably, the reduction occurs without a prior deprotonation of the car ...

Stay positive: catalysis with 1,3,2-diazaphospholenes

Nicolai Cramer, John Henry Reed, Johannes Klett

P-Hydrido 1,3,2-diazaphospholenes (DAPs) are a class of nucleophilic molecular hydrides capable of addition to a variety of substrates. They can be turned over with terminal reductants and emerged over the last few years as powerful and versatile catalysts ...

A 1,3,2-Diazaphospholene-Catalyzed Reductive Claisen Rearrangement

Nicolai Cramer, Pavel Alexandrovich Donets, John Henry Reed, Solène Florie Miaskiewicz

1,3,2-Diazaphospholenes (DAPs) are an emerging class of organic hydrides. In this work, we exploited them as efficient catalysts for very mild reductive Claisen rearrangements. The method is tolerant towards a wide variety of functional groups and operates ...
