New alkyl derivatives of the nido-dicarbapentaborane, 1,2-C(2)B(3)H(7), and arachno-carbapentaborane, 1-CB(4)H(10), have been identified as the main volatile carbaborane products in quenched gas-phase reactions of tetraborane(10), B(4)H(10), with alk

Merrifield-bound o-cresol undergoes electrophilic aromatic chlorination using SO2Cl2 leading to para/ortho ratios in excess of 50, the highest such ratio reported for this chlorinating agent. Model studies suggest that this significant para/ortho rat

The gas-phase reaction between 1-MeB5H8 and propyne at 230°C yields methyl derivatives of nido-2,3-dicarbahexaboranes and closo-2,4-dicarbaheptaboranes. The reaction between 1-MeB5H8 and 2-pentyne at 190°C gives analogous alkyl nido-carbaboranes (b

The reaction between Na 2 [ nido -6,9-C 2 B 8 H 10 ] (glyme, RT, 24 h) and PCl 3 produced the neutral phoshadicarbaborane nido -7,8,11-PC 2 B 8 H 11 (35%), which can be quantitatively deprotonated by proton sponge to give the corresponding [7,8,11- n
