Description / Table of Contents:
Reactions of trans-Difulminatobis(triphenylphosphine)platinum(II)The thermally very stable fulminato complex (Ph3P)2Pt(CNO)2 (1) rearranges under mild conditions to the isomeric isocyanato complex (Ph3P)2Pt(NCO)2 in the presence of organic carbonyl compounds which act as catalysts. (Ph3P)2Pt(NCS)2 is obtained from 1 and organic thiocarbonyl compounds. 1 is reduced by phosphines to the corresponding cyanide trans-(Ph3P)2Pt(CN)2. The safe preparation of a number of fulminato complexes (R3E)2M(CNO)2 (M=Pd, Pt; E=P, As, sb), (Ph3P)2Pt(X)CNO (X + H, Me, CN, NCO), and (Ph3P)2Rh(CO)CNO by use of [AsPh4]CNO is reported.
Notes:
Das thermisch sehr stabile (PhP)2Pt(CNO)2 (1) läßt sich katalytisch in Gegenwart von organischen Carbonylverbindungen unter milden Bedingungen zur Isocyanatoverbindungen (Ph3P)2Pt(NCO) 2 isomerisieren. 1 liefert mit organischen Thiocarbonylverbindungen (Ph3P)2Pt(NCS)2. Mit Phosphinen wird 1 zur entsprechenden Cyanoverbindung trans-(Ph3P)2Pt(CN)2 reduziert. Über die gefahrlose Darstellung verschiedener gemischter Fulminatokomplexe (R3E)2M(CNO)2 (M=Pd, Pt; E=P, As, Sb), (Ph3P)2Pt(X)CNO (X=H, Me, CN, NCO) und (Ph3P)2Rh(CO)CNO unter Verwendung von [AsPh 4]CNO wird berichtet.
