(94) We emphasize that the rate constants k1−k6 in the final model
are intended solely to provide a qualitative fit of temporal
concentration data in support of the global mechanistic picture for
the dehydrocoupling reaction, including autocatalysis and parallel
catalysis. Many of the rate constants are telescoped steps, some to
termolecularity with notional irreversibility, and should not be
interpreted in isolation or indeed in a quantitative manner.

(97) Dielectric constants: difluorobenzene, 13.8; CH2Cl2, 8.9; THF,
7.4; acetone, 21. Solubility of NaCl in acetone = 4.2 × 10−3 g/kg.
(98) Adventitious fluoride, or hydroxide, potentially could act in the
same way. However, as we pretreat the difluorobenzene by stirring
over alumina (to remove fluoride), then CaH2 (to remove water), and
finally distilling under vacuum, we suspect the levels of F− or H2O
would be low and also not reproducible. Although fluoride can be
generated from addition of strong nucleophiles, such as cyanide, to
fluoroaromatics [see: Sun, H.; DiMagno, S. G. J. Am. Chem. Soc. 2005,
127, 2050 ], it is unlikely this is occurring here. We see no evidence for
C−F activation of the fluoro-aromatic in these systems [see, for
example: Panetier, J. A.; Macgregor, S. A.; Whittlesey, M. K. Angew.
Chem., Int. Ed. 2011, 50, 2783 ] that might also generate a fluoride on
the metal. Such reactivity would also be inconsistent with our kinetic
model. Trace chloride thus appears to be the most reasonable
candidate.

(101) In an open system 13-Cy is also a good catalyst (ToF50 = 75
h−1). However, there appears to be an induction period before catalysis
starts.

NOTE ADDED IN PROOF
■
Highly organized metal templated transition states that involve
hydrogen−bonding of additional substrate, related to the
BH···HN interactions implied in this paper, have recently
been suggested to occur in intermolecular styrene hydro-
amination. See: Brinkmann, C.; Barrett, A. G. M.; Hill, M. S.;

outer-sphere interactions do not directly lead to H2 elimination from
