Platinum complexes derived from b-silyamines

Abstract

This invention relates to new cis diamino platinum complexes; to compositions comprising these complexes; and to processes for their utility as fungicides, bacteriocides and as inhibitors of the growth of cancer in warm-blooded animals, wherein the complex is of the formula: [B(CH.sub.2).sub.n NH.sub.2 ].sub.2 Pt-M and ##STR1## wherein Pt is platinum II or platinum IV; M is selected from Y.sub.2, cyclic ##STR2## cyclic ##STR3## and cyclic ##STR4## when Pt is platinum II and X.sub.4 when Pt is platinum IV; each a is independently 1 or 2; n is from 0-3; each Y is independently --Cl, --Br, --I, --OH, --ONO.sub.2, --OSO.sub.3 and ##STR5## each X is independently selected from Y and two equatorial X's can together further be cyclic ##STR6## or cyclic ##STR7## each B is independently selected from aminoalkyl(dialkylsily), aminoalkyl(diphenylsilyl), triphenylsilyl, trialkylsilyl, aminoalkyl(alkyl,phenylsilyl), 2-amino-3,3-dialkyl-3-silacyclo-alkyl, 2-amino-3,3-diphenyl-3-silacycloalkyl, 2-amino-4,4-dialkyl-4-silacycloalkyl, 2-amino-4,4-diphenyl-4-silacycloalkyl and 1-aminoalkyl-1-silacycloalkyl; each R is independently selected from hydrogen and Z substituted and unsubstituted alkyl, alkenyl, cycloalkyl, cycloalkenyl, alkynyl and aryl, provided that two R's attached to the same or adjacent carbon atoms, or two R's attached through different carbon atoms to the silicon atom, can form Z substituted or unsubstituted alkyl or aryl cyclic ring; and, Z is selected from haloge
