A DRAMATIC EFFECT OF A CATALYTIC AMOUNT OF LEAD ON THE SIMMONS-SMITH REACTION AND FORMATION OF ALKYLZINC COMPOUNDS FROM IODOALKANES - REACTIVITY OF ZINC METAL - ACTIVATION AND DEACTIVATION
K. Takai et al., A DRAMATIC EFFECT OF A CATALYTIC AMOUNT OF LEAD ON THE SIMMONS-SMITH REACTION AND FORMATION OF ALKYLZINC COMPOUNDS FROM IODOALKANES - REACTIVITY OF ZINC METAL - ACTIVATION AND DEACTIVATION, Journal of organic chemistry, 59(10), 1994, pp. 2671-2673
A trace amount of lead found in zinc derived from the pyrometallurgy s
melting method decreases the reactivity of zinc toward diiodomethane a
nd iodoalkanes substantially, and this negative effect can be suppress
ed by the addition of a catalytic amount of Me(3)SiCl.
