REGIOSELECTIVE ATTACK OF A SOFT CARBON NUCLEOPHILE AND HYDROGEN-SULFIDE AT THE CENTRAL CARBON OF A BETA-SUBSTITUTED ETA(3)-ALLYL TO RESPECTIVELY FORM ETA(3)-TMM AND NEW METALLACYCLIC THIACYCLOBUTANE COMPLEXES
Fy. Tsai et al., REGIOSELECTIVE ATTACK OF A SOFT CARBON NUCLEOPHILE AND HYDROGEN-SULFIDE AT THE CENTRAL CARBON OF A BETA-SUBSTITUTED ETA(3)-ALLYL TO RESPECTIVELY FORM ETA(3)-TMM AND NEW METALLACYCLIC THIACYCLOBUTANE COMPLEXES, Organometallics, 16(5), 1997, pp. 822-823
The cationic beta-substituted allyl complexes {Pt(PPh(3))(2)[eta(3)-CH
2C(OE)CH2]}(+) (E = silyl, alkyl, acyl) undergo the substitution of th
e carbon nucleophile for OE at the allyl central carbon to transform i
nto eta(3)-TMM complexes or undergo addition by hydrogen sulfide to yi
eld new metallathiacyclobutane complexes.
