She is developing a general platform for the in situ tagging of natural product mixtures to enable subsequent visualization by fluorescence imaging or stimulated Raman scattering microscopy.
Bimodal product mixtures are obtained, consisting of block copolymer as well as PPV homopolymer.
Tertiary amines and BPO gave low yields of the corresponding N-oxide and complex product mixtures, presumably via radical decomposition.
As the authors point out, it is therefore partly good fortune that their machine selectively prepares each of the four possible products (even if only as the major component of product mixtures) in the different reaction sequences.
The hydrogenation of m-xylene yielded steroisomeric product mixtures of the saturated 1,3-dimethylcyclohexane (1,3-DMCH), cis- and trans-1,3-DMCH.
No manganese was detected in the product mixtures, showing that the mediator manganese is confined inside the Pt-Nafion, and does not contaminate the products.
The analysis of product mixtures further indicated that rat liver S9 metabolism involved deacetylation of O-acetyl groups in the case of 4- 3- 2-hydroxyethoxy-4-amino phenylazo -N,N-bis 2-acetoxyethyl)aniline.
Product mixtures were analyzed with a newly developed dual-detector GPC method in which the linear byproducts were end-labeled with a UV-absorbing group and separately detectable with a UV detector.
The product mixtures were then imaged using a smartphone (Samsung, Galaxy A7, China).
Identifying unknown structures from the mass spectra of natural product mixtures has been a desirable yet unresolved issue in metabolomics.
LC/MS analysis of the crude product mixtures confirmed the presence of the desired 4-CC products.
