A study was made of the norbornadiene (NBD) to quadricyclene (Q) conversion in the presence of Cu(P(CH/sub 6/H/sub 5/)/sub 3/)/sub 2/BH/sub 4/, Cu(P(C/sub 6/H/sub 5/)/sub 2/(CH/sub 3/))/sub 3/BH/sub 4/, and Cu(diphos)BH/sub 4/ (diphos is 1,2-bis(diphenyl-phosphino)ethane). The first two compounds were approximately 60 to 90 times more effective than the latter compound in sensitizing the production of Q. Furthermore, the mechanism of sensitization appears to be fundamentally different from that involving CuX salts (where X is Cl, Br, I, or C/sub 2/H/sub 3/O/sub 2/). (JSR)
