The di-n-nonyl phenylthioboronate was prepared by reacting the Na salt of nonannethiol with dichlorophenylborane. A high-vacuum line was constructed in which the thioboronate esters can be purified without heating the distillation pot, thus preventing pyrolysis. A small dry-box is being constructed with an inlet tube and cold trap as well as space for storage and manipulation of IR sample cells. The B3SCN3N3H3 compound was most sensitive in moist air, and vacuum manipulation appears to be mandatory to insure a good product. B-trichloro-N-triphenyl-borazine was reacted with KCN in benzene solvent in an attempt to replace the Cl with thiocyanate groups. Varying results from this preparation prompted a second preparation with an extended reaction time. A crop of white slight tan crystals were obtained. An investigation was started on the IR assignments of some borazine compounds. All compounds studied had one intense band around 11400 or 11450 cm. which has been assigned to the inplane skeletal vibration of the 6-membered B-H ring.
