On 8th August this year, I posted on a fascinating article that had just appeared in Science (DOI:10.1126/science.1188002), in which the crystal structure was reported of two small molecules,1,3-dimethyl cyclobutadieneandcarbon dioxide, entrapped together inside a calixarene cavity. Other journals (e.g.Nature Chemistry, DOI:10.1038/nchem.823) ran the article as a research highlight (where the purpose is not a [...]

Earlier this year, Barboiu made the astonishing claim of the x-ray characterization of 1,3-dimethylcyclobutadiene, brought about by the photolysis of 4,6-dimethyl-α-pyrone encapsulated in a guanidinium-sulfonate-calixarene crystal (Reaction 1).1 I had...
These are my reactive chemistry links for:Caged molecules – Can you trap two small molecules at the same time in a hollow molecular cavity and still call them two separate molecules, or is something more bizarre happening in this tiniest of reaction vessels....
The notoriously strained and unstable cyclobutadiene ring is currently creating quite a stir. In a recent Science report which we highlighted here Mihail Barboius group described the preparation of a calixarene-based matrix, in which they encapsulated a dimethyl--pyrone....
