STUDIES ON HETERO-MACROCYCLIC POLYETHER (Ⅱ). THE SYNTHESIS OF PLATINUM COMPLEX OF 10-SELENABENZO-15-CROWN-5 AND ITS CATALYTIC BEHAVIOR IN HYDROSILYLATION

The title complex (PtL_2Cl_2) was synthesized by reacting 10-selenabenzo-15-crown-5 (L) with potassium chloroplatinite. Its catalytic activity for the hydrosilylation of olefins by triethoxysilane, was investi gated.

STUDIES ON HETERO-MACROCYCLIC POLYETHER(1).THE SYNTHESIS OF 10-SELENA BENZO-15-CROWN-5

The synthesis of a new type of hetero-macrocyclic polyether 2,3-henzo-1,4,7,13-tetraoxa-10-selenacyclopentadeca-2-ene is deseribed.
