Represented by dimerization of chalcones and cinnamic acid derivatives, photo [2+2] cycloaddition is a unique strategy to construct cyclobutanes, the building blocks for a variety of biologically active molecules existing in nature. However, most attempts for the above [2+2] addition focused on solid-state, molten-state or host-guest systems under ultraviolet light irradiation in order to overcome the competition of facile geometric isomerization of nonrigid olefins. Here, we report a general and simple method to realize the intermolecular [2+2] dimerization reaction of these acyclic olefins to construct cyclobutanes in a highly stereo- and diastereoselective manner in solution under visible light, which provides an efficient solution to the long pending problem.
This research output has an Altmetric Attention Score of 16. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 01 October 2024.
All research outputs
#3,008,862
of 34,546,575 outputs
Outputs from Angewandte Chemie. International Edition
#6,422
of 61,859 outputs
Outputs of similar age
#43,952
of 375,367 outputs
Outputs of similar age from Angewandte Chemie. International Edition
#128
of 799 outputs
Altmetric has tracked 34,546,575 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 91st percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 61,859 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.7. This one has done well, scoring higher than 89% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 375,367 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 88% of its contemporaries.
We're also able to compare this research output to 799 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 83% of its contemporaries.
