摘要：

Under metalation conditions the 2,4-pentadienylboranes 2,4-C5H7B(NR2)2 (R = Me, Et) and 2,4-C5H7B(O2C2Me4) undergo an electrocyclic ring closure to form borabenzene derivatives. This novel reaction provides a far more efficient access to borabenzene chemistry than previous methods. The dimethylamino derivative [Li{Me2N(CH2)3NMe2}](C5H5BNMe2) is the first boratabenzene salt to be structurally characterized.
