  flash photolysis techniques as well as chemically induced dynamic nuclear polarization (CIDNP). Irradiation of acetonitrile solutions of 9,lO-dicyanoan- thracene (DCA), 2,6,9,1O-tetracyanoanthracene (TCA), or chloranil (Chl) in the presence of Azo-Q results in rapid and efficient deazatization to afford N. Similar irradiation of DCA, TCA, and Chl in the presence of Azo-N yields N and Q. CIDNP experiments

• Thermal Decomposition of a Series of 1,2-Diazetines

  A homologous series of tricyclic diazetines (6a-c), differing by the number of methylene groups in the saturated bridges of the fused carbon bicycles, was synthesized. The DeltaH(not equal) of decomposition for each of the diazetines to afford N-2 and the corresponding alkene was determined experimentally: 6a, 31.7; 6b, 39.3; 6c, 38.8 kcal/mol. The ground-state strain energy of each diazetine was estimated utilizing computationally obtained DeltaH(f)'s for each of the experimentally investigated diazetines as well as several other diazetines whose DeltaHs(not equal,) had been previously reported in the literature. The sum of the ground-state strain energies and DeltaHs(not equal,) of decomposition for all of the diazetines was nearly constant, with an average value of 59 kcal/mol, suggesting that all of the diazetines decompose via the same mechanism. Generally, the higher the ground-state strain energy of the diazetine, the less the DeltaH(not equal) for decomposition. The decomposition transition states for 6a-c and 7 were modeled computationally at the RB3LYP/6-311+G(3df,2p)//UB3LYP/6-31+G(d,p) level. The agreement of the experimentally determined DeltaH(not equal) values with transition-state energies obtained computationally supports the reaction mechanism originally proposed by Yamabe that the elimination process occurs by an unsymmetrical, yet concerted, transition state with strong biradical character.

• Rh(III)-Photosensitized Interconversion of Norbornadiene and Quadricyclane
  作者：Gregory W. Sluggett、Nicholas J. Turro、Heinz D. Roth

  DOI：10.1021/jp972007h

  日期：1997.11.1

  The utility of two Rh(III) diimine complexes, Rh(phen)(3)(3+) and Rh(phi)(2)(phen)(3+) (phen = 1,10-phenanthroline, phi = 9,10-phenanthrenequinone diimine), as sensitizers for the interconversion of norbornadiene (N) and quadricyclane (Q) has been investigated using steady-state photochemical and laser flash photolysis (LFP) techniques. Irradiation of acetonitrile solutions of Rh(phen)(3)(3+) and N causes slow conversion to Q. The reaction is reversible; irradiation of Rh(phen)(3)(3+) in the presence of Q leads to N. Irradiation of acetonitrile solutions of Rh(phi)2(phen)3+ and Q yields N. However, this reaction is irreversible; irradiation of the Rh(In) complex in the presence of N fails to afford Q. Irradiation of methanol solutions of either Rh(III) complex in the presence of N or Q affords minor amounts of two methanol-C7 adducts but fails to quench the N-Q interconversion reaction. The results are consistent with N-Q interconversion via an exciplex intermediate. The Rh(III)-sensitized deazatization of two cyclic azoalkane derivatives (Azo-N, Azo-Q) of N and Q was also investigated. Deazatization was achieved by Rh(phen)(3)(3+) but not Rh(phi)(2)(phen)(3+) sensitization. The results are consistent with a mechanism involving triplet energy transfer, but the involvement of exciplex intermediates cannot be ruled out. Bimolecular rate constants for quenching of the Rh(III) excited states by N, Q, Azo-N, and Azo-Q were determined by LFP.
