Fragmentation of 1-hydroxy-2-(5H-dibenzo[a,d]cyclohepten-5-yl)-1-phenylethyl cation in superacid
摘要:
The 1-hydroxy-2-(5H-dibenzo[a,d]cyclohepten-5-yl)-1-phenylethyl cation generated under ''long life'' conditions undergoes fragmentation to afford 5H-dibenzo[a,d]cycloheptenyl- and methylphenylhydroxycarbinyl cations but does not undergo carbocationic cyclization.
