A protocol for the Suzuki-Miyauracoupling of heteroaryl boronic acids and vinyl chlorides that minimizes protodeboronation is described. A combination of catalytic amounts of Pd(OAc)(2) and SPhos in conjunction with CsF in isopropanol effectively affords a variety of coupled products. Surprisingly, a dramatic temperature dependence in product selectivity was observed.

Merrifield resin and then functionalized by means of numerous reactions including transition‐metal‐catalyzed cross‐couplings. In the final step the fluorinating cleavage reaction provides the trifluoromethylarenes in good yields and high purities.
