T. Jelinek et al., THE 1ST CLUSTER AZATHIABORANES - ISOLATION AND CHARACTERIZATION OF 8-VERTEX HYPHO-7,8-NSB6H11 AND 10-VERTEX ARACHNO-6,9-NSB8H11, Journal of the Chemical Society, Chemical Communications, (21), 1993, pp. 1628-1629
Reaction of n-butyl nitrite with arachno-4-SB8H12 in diethyl ether or
with nido-6-SB9H11 in benzene yields the first cluster azathiaboranes,
hypho-7,8-NSB6H11 and arachno-6,9-NSB8H11.
