IS IT POSSIBLE TO STABILIZE COMPLEXES WITH A TUNGSTEN-PHOSPHORUS TRIPLE BOND

2)(t)C(2)P(2))W(CO)(5)}{eta(2)-(Bu(t)CP)W(CO)(5)}] 1 is prepared by tr eatment of Bu(t)C=P with [W(CO)(5)THF]; the reaction of [W-2(OBu(t))(6 )] With Bu(t)C=P in the presence of [M(CO)(5)THF] (M = Cr, W) affords novel compounds of the type [(Bu(t)O)(3)W=P-->M(CO)5] (M = Cr, W), the first examples of a formal W=P containing complex.
