The liquid-phase halogenation of a number of hydrocarbons and of 1-chlorobutane by N-halogenobis-(trialkylsiyl)amines has been studied using product analysis techniques. The reactions take place by free radical chain mechanisms which involve the propagation steps generalised in equation (A) and (B)(X = Br or Cl). At 353 K, the molar reactivities of toluene (benzylic C–H) and cyclohexane towards (R3Si)2N·+ RH →(R3Si)2NH + R·(A), R·+(R3Si)2NX → RX +(R3Si)2N·(B)(Me3Si)2N· are approximately equal… CONTINUE READING
