Must Read Papers 2015. Part 2.

help 2At the end of 2015 I wrote a post (Must read papers 2015) including my favourite paper of the year and recommendations of a few nice reviews/highlights to read during Christmas. During 2015 I selected several papers I wanted to write about in the blog but unfortunately I have less time than I would like and I couldn’t write a line about many of them. Now 2015 is gone and I already have a few nice papers selected this year to comment in the blog. So all these nice papers are piling up and haunt me in my dreams because I don’t have enough time (or maybe because I’m just lazy).

To make a long story short I have decided to write a follow-up post of the Must read papers 2015 to comment a little bit on the best papers I selected during 2015 that for one reason or the other attracted my attention (click on the pictures if you want to go to the paper’s websites).

The first two papers of the post fit perfectly in the section Cool Synthesis under the topic Impossible Molecules. The Impossible Molecules topic is dedicated to molecules with exotic structures, elusive molecules and synthetically challenging molecules in general.  The first paper describes the first example of an amazing corannulene derivative bearing an internal heteroatom. The second paper describes a creative strategy to stabilise long cumulenes with a phenanthroline-based macrocycle.

If you have ever read this blog before, you already know I’m a bit (just a bit) obsessed with halogenating reactions so you will find several posts on the topic. There are 2 papers I couldn’t write about during 2015 that I want to highlight. The first one describes a one-pot vicinal fluorination-iodination of arynes using the diphenyliodonium salt as a catalyst and CsF as a fluorine source. The second paper describes the synthesis of the molecules Halomon, Plocamenone and Isoplocamenone using a dihalogenating reaction I wrote about in a previous post.

Another of my obsessions is the chemistry of Frustrated Lewis Pairs (FLP), and just as I said in one of my previous posts “This is not the first time and probably will not be the last time I post about Frustrated Lewis Pairs”. One of the papers I didn’t have time to write about is this nice contribution by Stephan’s group on the catalytic hydrogenation and reductive deoxygenation of ketones and aldehydes.

The next paper is another creative contribution by Alcarazo and coworkers. The paper describes an interesting alternative to hipervalent iodine species, Dihalo(imidazolium)sulfuranes that are versatile electrophilic group-transfers reagents.

The last paper I want to mention in this post caught my attention because of the interesting fact that the selectivity of the two products obtained in a copper-catalysed arylation is controlled by the choice of the reaction vessel.
