Robert K. Boeckman, Jr.*, Ping Ge, and Jessica E. Reed New Heterocyclic Precursors for Thermal Generation of Reactive, Electron-Rich 1,2-Diaza-1,3-butadienes. Page 3647. In the Table of Contents graphic, the Abstract graphic, the graphics above Tables 1 and 2, and Scheme 3, the structure of either unlabeled or labeled 6 should appear as follows:

In the Table of Contents graphic, the Abstract graphic, and Scheme 3, the unlabeled structure above the second arrow should appear as follows:

Page 3647, Abstract, line 2. N-phenyldiazamaleimide should read N-phenylmaleimide. Page 3648, column 2, Table 1. The legend for the sixth substrate which reads R2 ) OPhNO2o should read R2 ) OPhNO2p. Page 3649, column 1, paragraph 4. In sentence 2, Nphenylmaleiimide should read N-phenylmaleimide. Page 3649, column 1, Table 2. The legend under structure 6 and the heading of the third column should read 6a,f,g. Page 3650, column 2. Compound numbers in the Supporting Information Available statement should read 2a, 2f, 3b, 4a, 4f, 6a, 6d, 6e, 6f, 8, 10, and 11. NOTE: The Supporting Information contained incorrect compound number designations. The Supporting Information has been revised to correct the compound numbering. Supporting Information Available: General experimental procedures and characterization data for 2a, 2f, 3b, 4a, 4f, 6a, 6d, 6e, 6f, 8, 10, and 11.
