Polyboranes alkylation

Alkyl derivatives of the nido-carborane, 2-CB5H9, are found as side products from the thermal (200°C) reaction between pentaborane (9) and acetylenes (see 5.3.2.7.3). These alkyl derivatives of 2-CB5H9 are formed from the internal 1,1 addition of two B—H bonds of the polyborane to the acetylene. 

Of the 33 papers presented at the symposium 32 are included in this volume. They are of two general types. One type discusses inorganic compounds exhibiting a specific property, most frequently electrical or photochemical. The second type reviews recent developments in the synthetic chemistry of a class of inorganic compounds— most often transition metal or lanthanide complexes— which are of potential interest to persons looking for new systems with unusual properties. Classes of compounds covered by this second type include metal alkyls, metal alk-oxides, metal alkylamides, metal chelates, and metal clusters as well as metal complexes with polyboranes, polyphosphines, macrocyclic derivatives, di- and triketones, and polypyrazolylborates as ligands.
