Abstract
In this study, DFT calculations were performed in order to identify the reaction products of the photochemical dimerization of indones. Calculations allowed us to assume that all tested reactions occurred in the first excited singlet state. The irradiation of 2-phenyl-5-nitroindone gave the main product, the <i>anti-cis</i> head-to-tail dimer, while the other two compounds found in the experiments were the <i>syn-cis</i> head-to-head dimer and the <i>anti-cis</i> head-to-tail dimer. The irradiation of 2-phenylindone gave the main product, <i>syn-cis</i>-head-to-tail dimer, while the minor products were <i>anti-cis</i>-head-to-tail and <i>anti-cis</i>-head-to-head dimer. The photochemical dimerization of 2-methyl-3-phenylindone gave the main product, <i>anti-cis</i>-head-to-tail dimer, while the minor component of the mixture was <i>syn-cis</i>-head- to-head dimer.
期刊介绍:
Aims & Scope
Letters in Organic Chemistry publishes original letters (short articles), research articles, mini-reviews and thematic issues based on mini-reviews and short articles, in all areas of organic chemistry including synthesis, bioorganic, medicinal, natural products, organometallic, supramolecular, molecular recognition and physical organic chemistry. The emphasis is to publish quality papers rapidly by taking full advantage of latest technology for both submission and review of the manuscripts.
The journal is an essential reading for all organic chemists belonging to both academia and industry.
