2-Chloronorbornadiene affords with 4-phenyltriazolinedione the homocycloadduct (1a) regioselectively as major product, along with small yields of the (2+2)-cycloadduct (2a), the dipolar rearrangement product (3a), and the ring insertion product (4a), while 2-trimethylsilyloxynorbornadiene leads to the ene-product (7c).
