J. Jeon et al., Synthesis and reactivity of an efficient 1,2-dehydrocarborane precursor, phenyl[o-(trimethylsilyl)carboranyl]iodonium acetate, CHEM COMMUN, (20), 2001, pp. 2110-2111
The reaction of [o-(trimethylsilyl)carboranyl]lithium with IPh(OAc)(2) in d
iethyl ether affords an efficient 1,2-dehydro-o-carborane precursor 4: the
facile 2 + 4 cycloaddition of 4 with dienes in the presence of the desilyla
ting agent is reported.
