    Atom-Transfer Cyclization with CuSO<sub>4</sub>/KBH<sub>4</sub>: A Formal “Activators Generated by Electron Transfer” Process Also Applicable to Atom-Transfer Polymerization

    The 4-<i>exo</i> and 5-<i>exo-trig</i> atom-transfer cyclizations of <b>1</b>,<b> 8a</b>–<b>e</b>, <b>9</b>, <b>12</b>, and <b>13</b> can be mediated with as little as 0.05 mol % of Cu­(TPMA)­SO<sub>4</sub>·5H<sub>2</sub>O in the presence of 2.5 mol % of borohydride salts in 10 min at room temperature in air. This formal “activators generated by electron transfer” (AGET) procedure utilizes a cheap and oxidatively stable copper source (CuSO<sub>4</sub>·5H<sub>2</sub>O) and can be carried out in environmentally benign solvents (EtOH). It is possible to alter the product distribution in the 5-<i>endo</i> radical–polar crossover reactions of <b>10a</b>,<b>b</b> and <b>11</b> by tailoring the amount of borohydride. Cyclization onto alkynes <b>14</b> and <b>15</b> is also possible in only 20 min. Controlled radical polymerization of styrene, with increased rates over conventional atom-transfer radical polymerization (ATRP), can be carried out in a controlled fashion (Mn, PDI) using either CuBr or CuSO<sub>4</sub>·5H<sub>2</sub>O and Bu<sub>4</sub>NBH<sub>4</sub>
