Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Dalton Transactions called Lithium heterocuprates: the influence of the amido group on organoamidocuprate structures, Author is Bomparola, Roberta; Davies, Robert P.; Hornaeur, Stefan; White, Andrew J. P., which mentions a compound: 75732-01-3, SMILESS is [Cu]C1=C(C)C=C(C)C=C1C, Molecular C9H11Cu, Synthetic Route of C9H11Cu.
Li organoamidocuprates LiCuR(NR’2) are an important class of organocopper reagents and found widespread application in conjugate addition and other bond-forming reactions. The dependence of the structures and equilibrium of these species on the steric and electronic properties of the amido group is reported in both the solid state and in solution Three different cuprate complexes were crystallog. characterized: the organoamidocuprate [Cu2Li2Mes2TMP2] (2) (TMP = 2,2,6,6-tetramethylpiperidide) which is shown to adopt a head-to-tail conformation; [Cu2Li2(N(CH2Ph)CH2CH2NMe2)4] (3) which is a homoamidocuprate and contains addnl. coordination of the Li centers from intra-mol. tertiary amine groups; and the diastereomeric organoamidocuprate [Cu2Li2Mes2(N(R-CH(Ph)Me)(CH2CF3))2] (4) which adopts a head-to-head conformation. Complex 4 is unique in being the 1st crystallog. characterized example of a head-to-head isomer of a heterocuprate, and its structure also has implications for the use of scalemic amidocuprates in asym. induced conjugate addition The solution equilibrium of all new complexes also were studied using 7Li NMR spectroscopy, and in each case the species observed in the crystal structure was shown to also be the predominant isomer in solution
