“…Anhydrous CH 3 CN (H 2 O Ͻ 0.001 %), CH 2 Cl 2 (H 2 O Ͻ 0.001 %), and DMF (H 2 O Ͻ 0.005 %) were obtained from Aldrich and degassed, freshly distilled, and stored over molecular sieves under nitrogen. TiCl 4 ·2thf [50] and LiSPh [51] were prepared according to literature procedures. CuCl was washed with HCl, CH 3 OH, and diethyl ether to remove traces of CuCl 2 , then dried under vacuum.…”
