The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate(SMILESS: [F-][B+3]([F-])([F-])[F-].C12=C3[Rh+]14567(C8=C5C9C6=C7C8C9)C%10=C4C2CC3%10,cas:36620-11-8) is researched.Computed Properties of C14H8BF4Rh. The article 《Functionalized pyrroles from vinylaziridines and alkynes via rhodium-catalyzed domino ring-opening cyclization followed by C=C bond migration》 in relation to this compound, is published in Tetrahedron. Let’s take a look at the latest research on this compound (cas:36620-11-8).
In the presence of Rh(nbd)2BF4 (nbd = norbornadiene), an aziridinylpropenoate I underwent cycloaddition reactions with aryl alkynes such as RCCH (R = Ph, 4-MeC6H4, 4-MeOC6H4, 4-ClC6H4, 4-F3CC6H4, 4-MeCOC6H4, 4-EtO2CC6H4, 2,4,6-Me3C6H2, 1-naphthyl) followed by isomerization of the intermediates with DABCO to yield arylpyrrolepropanoates such as II (R = Ph, 4-MeC6H4, 4-MeOC6H4, 4-ClC6H4, 4-F3CC6H4, 4-MeCOC6H4, 4-EtO2CC6H4, 2,4,6-Me3C6H2, 1-naphthyl). An aziridinylpropenone underwent analogous cycloaddition and isomerization reactions with phenylacetylene to yield a phenylpyrrolylpropanone.
