Among the available methods to increase the molecular complexity, sigmatropic
rearrangements occupy a distinct position in organic synthesis. Despite being known for …

Diazo compounds are very versatile reagents in organic chemistry and meet the challenge
of selective assembly of structurally complex molecules. Their leaving group is dinitrogen; …

A transition‐metal‐free difluoromethylenation of diazo compounds that proceeds under mild
conditions has been developed and is based on the use of TMSCF2Br as the …

Owing to its tremendous preparative importance, rhodium carbene chemistry has been
studied extensively during past decades. The invoked intermediates have, however, so far …

A new reaction for the rhodium‐catalyzed geminal‐difunctionalization‐based fluorination is
presented. The substrates are aromatic and aliphatic diazocarbonyl compounds. As the …

[2, 3]-Sigmatropic rearrangement processes of allylic ylides or their equivalents can be
applied to a variety of different substrates and generate products of wide …

Diazo compounds, due to their diverse and rich chemical properties, have remained as one
of the major domains in the organic chemistry research for long time. In the past two …

Diazo compounds are versatile organic compounds and have become increasingly
important in organic synthesis and many other fields. In particular, α-diazocarbonyl …

We have developed catalyst-controlled regiodivergent rearrangements of onium-ylides
derived from indole substrates. Oxonium ylides formed in situ from substituted indoles …

Traditional rhodium carbene chemistry relies on the controlled decomposition of diazo
derivatives with [Rh2 (OAc) 4] or related dinuclear Rh (+ 2) complexes, whereas the use of …
