Reaction Conditions

Reaction Steps

In an argon filled glove box, a 5.0 mL wheaton microreactor was charged with [Ir(cod)(OMe)]2 (1.98 mg, 1.5 mol%), L1 ligand (2.1 mg, 3.5 mol%), B2pin2 (50.8 mg, 1.0 equiv.), KOtBu (1.0 mg, 4.5 mol%) and dry THF (1.0 mL). The reaction mixture was stirred for 2 minutes at room temperature. To this mixture, N-(tert-butyl)-N-methylbenzamide (38.3 mg, 0.2 mmol) was added. The microreactor was capped with a teflon pressure cap and placed into pre-heated aluminum block at 80 oC. The reaction mixture was stirred for 12 h. After completion (judged by GC/MS), THF was removed under reduced pressure and chromatographic separation with silica gel (15% ethyl acetate in hexane as eluent) gave the meta-borylated product 4c (41.2 mg, 65%) as white solid.
