(11) Data for 2, 4, and 5 were collected with a Bruker Kappa Apex II
CCD diffractometer at 100 K, with a Nonius KCCD diffractometer at
150 K, and on I19 (EH1) at the Diamond Light Source at 150 K,
respectively. 2 and 4 were solved and refined using SHELXS/XL-97
(see: Sheldrick, G. M. Acta Crystallogr. 2008, A64, 112). 5 was
solved using SIR92 (see: Altomare, A.; Cascarano, G.; Giacovazzo, C.;
Guagliardi, A.; Burla, M. C.; Polidori, G.; Camalli, M. J. Appl. Crystallogr.
1994, 27, 435.) and refined using CRYSTALS (see: Betteridge, P. W.;
Carruthers, J. R.; Cooper, R. I.; Prout, K.; Watkin, D. J. J. Appl.
Crystallogr. 2003, 36, 1487). The crystallographic data for 2, 4, and 5
have been deposited with the CCDC as entries 823663, 823664, and
823665, respectively.

(15) The 11B chemical shifts and J(HB) coupling constants showed a
small dependence on the solvent (CD2Cl2, 1,2-C6H4F2, or 1,2-C6H4F2/
MeCN). See the Supporting Information.
