Résumé : | Aromatic organo‐tin compounds ArSnR3 have been synthesized with R = n‐butyl and R = i‐propyl. Increased bulk of the leaving group results in lower reactivity towards iodine, showing appreciable interactions between the incoming and leaving groups. A peri hydrogen atom induces a secondary steric acceleration, suggesting that the ground state for large R3Sn substituents in 1‐naphthyl systems is strained. This agrees with previous reports by EABORN et coll. [14] relating to the corresponding silicon and germanium compounds. Copyright © 1964 Verlag GmbH & Co. KGaA, Weinheim |
