The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 6-Bromo-2,3-dihydrobenzo[b][1,4]dioxine(SMILESS: BrC1=CC=C2OCCOC2=C1,cas:52287-51-1) is researched.Name: Bis(acetylacetonato)dioxomolybdenum(VI). The article 《Air-Stable PdI Dimer Enabled Remote Functionalization: Access to Fluorinated 1,1-Diaryl Alkanes with Unprecedented Speed》 in relation to this compound, is published in Angewandte Chemie, International Edition. Let’s take a look at the latest research on this compound (cas:52287-51-1).
This work features a remote arylation in less than 10 min reaction time at room temperature over a distance of up to 11 carbons. The unprecedented speed was enabled by the air-stable PdI dimer [Pd(μ-I)(PCy2t-Bu)]2, which in contrast to its PtBu3 counterpart does not trigger direct coupling at the initiation site, but regioconvergent and chemoselective remote functionalization to yield valuable fluorinated 1,1-diaryl alkanes. This study combined exptl. and computational studies rationalize the origins of switchability, which were primarily due to differences in dispersion interactions.
