The [3,3′-Co(1,2-C2B9H11)2]– anion as a platform for new materials: synthesis of its functionalized monosubstituted derivatives incorporating synthons for conducting organic polymers

Extraction with Metal Bis(dicarbollide) Anions

“…This consisted of the ring opening of the 8-dioxane-1 [8-O(CH2CH2)2O)-C2B9H10)(1'2'-C2B9H11)-3,3'-Co] zwitterion 42. Similar kind of reactions provides also the recently reported compound containing tetrahydropyrane ring [116]. As in the case of 41, the dioxane ring containing an oxonium oxygen atom can be easily cleaved by almost any nucleophile of choice [112][113][114][115] producing the species functionalized with various end groups attached to the hydrophobic anion 1 via a diethylene diglycol chain (see Scheme 3).…”

Synthesis, Characterisation, and X‐ray Crystal Structure of New NiII, PdII, and PtII Complexes of Tridentate Pyrazole‐Based Ligands with an NOS‐Donor Set

“…The RϪOH resonances shift to lower fields with decreasing temperature, as expected for this kind of process. [18] For the SϪ(CH 2 . [13] The IR spectra (4000Ϫ400 cm…”

Nucleoside–Metallacarborane Conjugates for Base‐Specific Metal Labeling of DNA

“…Ring opening in the cyclic ether attached to the [bis(1,2-dicarbollido)-3-cobalt(À1)] ion by simple nucleophiles has been described previously, [22][23][24][25] and recently the synthesis of a porphyrin-containing [bis(1,2-dicarbollido)-3-cobalt(À1)] ion was described, although application of the above method for complex biological molecules has not been pur- www.chemeurj.org sued. [26] Activation of the protected 2'-O-deoxynucleosides 2 a-d with sodium hydride results in deprotonation of thymine at the ring nitrogen 3-N and cytidine and adenine at 4-N and 6-N of the exo-amine group, respectively.…”
