Synthesis and reactivity of an efficient 1,2-dehydrocarborane precursor, phenyl[o-(trimethylsilyl)carboranyl]iodonium acetate.
The reaction of [o-(trimethylsilyl)carboranyl]lithium with IPh(OAc)2 in diethyl 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 desilylating agent is reported.
