A family of η5-CpFe(CO)2-substituted closo-carboranes was synthesized and characterized, including cyclic voltammetry measurements. Like the previously reported bimetallic compound 1,12-[η5-CpFe(CO)2]2-1,12-C2B10H10 (8), 1,10-[η5-CpFe(CO)2]2-1,10-

Reactions of both closo-9,12-I2-1,2-C2B10H10 and closo-9,10-I2-1,7-C2B10H10 with an excess of aryl magnesium bromide in the presence of [PdCl2(PPh3)2] afford the corresponding closo-9,12-(4-R-C6H4)2-1,2-C2B10H10 [R=H (1), Me (2), OMe (3), SMe (4), N(

The reaction of closo-1,12-bis(lithio)-1,12-dicarbadodecaborane(12) (1,12-bis(lithio)-p-carborane) with SO(2) formed closo-1,12-bis(lithiosulfinato)-p-carborane (10) in nearly quantitative yield. The latter was converted to closo-1,12-bis(sulfinic ac

Conventional methods of stabilizing fragments in cranial impression fracture include the use of threads, wires, plates, etc. A new approach to facilitate this surgery is the use of titanium clamps, presented here in five cases, including one with fro

Keine Explosion, sondern per-Borhydroxylierung tritt ein, wenn die ikosaedrischen Borhydride [closo-B12H12]2−, [closo-CB11H12]− oder closo-1,12-(CH2OH)2-1,12-C2B10H10 in 30proz. Wasserstoffperoxid unter Ruckflus erhitzt werden. Bei diesen Umsetzu

No explosion, but per-B-hydroxylation occurs if the icosahedral boron hydrides [closo-B12 H12 ](2-) (see picture), [closo-CB11 H12 ](-) , or closo-1,12-(CH2 OH)2 -1,12-C2 B10 H10 are refluxed in 30 % hydrogen peroxide. Thus, the three isoelectronic s

Facile, efficient, and economical is the exhaustive methylation of ortho-carborane, its isomers and its derivatives under Friedel–Crafts conditions utilizing MeI and AlCl3. Regioselectively, ortho-carborane yields the 4,5,7,8,9,10,11,12-octamethyl
