Hydroamination reactions by metal triflates: Brønsted acid vs. metal catalysis?

Catalytic hydroamination reactions involving the addition of carboxamides (X = CO), carbamates (X = CO(2)) and sulfonamides (X = SO(2)) to unactivated C=C bonds are briefly reviewed. Development in this field of catalytic research is briefly charted, followed by a discussion of possible mechanisms, including arguments to support the operation of both metal and Brønsted acid catalysis in these s...

Recent developments in the Reformatsky-Claisen rearrangement.

The rearrangement of allyl a-bromoacetates with Zn dust is known as the Reformatsky-Claisen rearrangement. Whereas the Ireland-Claisen rearrangement has been widely used in the synthesis of a diverse range of natural products, the Zn-mediated Reformatsky-Claisen rearrangement has not been utilized so often. In this article, we will provide an overview of recent advances in the Reformatsky-Clais...

The Baeyer-Villiger reaction: new developments toward greener procedures.

Developments toward the unmanned ship

This paper provides an overview of the initial position and rationale regarding the development of an unmanned ship. This is based on the proposal for the EU-funded project MUNIN (Maritime Unmanned Navigation through Intelligence in Networks). Based on the European vision of an autonomous ship, MUNIN’s understanding of autonomy, its contribution towards a sustainable maritime transport system a...
