Recently, it was shown that Piers’ borane [HB(C6F5)2]2 can induce rapid oligomerization reactions of arylacetylenes and arylallenes. Using phenylallene PhCH=C=CH2 and phenylacetylene PhCCH as typical substrates, the detailed mechanisms of borane‐induced oligomerization are disclosed by extensive sta...
