Interconversion of Volatile Boranes by Basic Reagents

Further Studies of the Tetraborane Carbonyl B4H8CO

“…Two distinctly different approaches by Schaef-fer also failed to produce any B3H7C0. 8 It is suggested that the dissociation 4 -B3H7 + BH3 makes good progress only in the presence of a base which can combine firmly with the very strong Lewis acid B3H7; otherwise the reaction B4Hi0 -* B4H8 + H2 is more probable.4 Indeed, we find that 4 has no appreciable influence on the decomposition of B4H8CO, showing that BH3 is not nearly so readily available from B4Hio as from B2H6.…”

Halogenated octahydroborate salts. New route to pentaborane(9)

“…(1) This research was performed at the Illinois Institute of Technology and forms part of a thesis submitted there by A. C. Lin in partial fulfillment of the requirements for the Ph.D. degree (2). Exchange is shown here as occurring via complete replacement of the original solvating water molecule generated by neutralization of the hydroxide ion.…”

Synthesis of octamethylcyclotetraphosphazene and hexamethylcyclotriphosphazene

“…[1][2][3][4][5][6][7] Addition of B2H6 to LiBcHg is a potentially useful reaction in that it can yield B6Hi0 and Bi0Hi4.8 We describe herein the preparation of B6Hi0 in a procedure which offers substantial advantages over previously published methods. [8][9][10][11][12][13] Experimental Section Methods and Materials.-Standard vacuum-line techniques were used in the manipulation of volatile materials. Nonvolatile materials were transferred in a drybox in a nitrogen atmosphere.…”
