In contrast with other types of carbene complex reaction discussed in this book, which mainly are tools for the synthesis of fine chemicals, the development of olefin metathesis was essentially driven by the petrochemical industry. [Pg.136]

Other reactions for which a discussion of their structure-reactivity behavior in terms of the PNS has provided valuable insights include nucleophilic addition and substitution reactions on electrophilic alkenes, vinylic compounds, and Fischer carbene complexes reactions involving carbocations and some radical reactions. [Pg.226]

Several heteroatom nucleophiles, for example, amines, alcohols, thiols, carboxylates, and dialkylphosphines, undergo Michael addition reactions with alkene- and alkyne-substituted carbene complexes. Reaction of alkyne-substituted chromium carbenes with urea affords products derived from Michael... [Pg.3221]

These exchange reactions of Fischer carbene complexes occur through tetrahedral intermediates, just like the transesterification of esters. Reaction of a Fischer carbene complex with an alcohol in the presence of base generates the same type of anionic intermediate that an ester does. This intermediate breaks down like an ester to form a new alkoxy-substituted carbene complex. Reactions of amines with Fischer carbene complexes occur similarly, but the high basicity of amines and the high electrophilicity of the carbene complexes alleviates the need for any additional base. [Pg.493]

Cp or Cp with elimination of N2 forming the corresponding carbenes Mn(CO)2(CR RML. The carbene precursor C H [C(N2)Ph]2 under similar conditions provides a bis-carbene complex. Reaction of the 7-membered carbocyclic carbene 69 with CO results in the n -ketene derivative 70. ... [Pg.248]

Various reactivities have been observed for cycloheptatrienylidene palladium complexes in the presence of nitrogen heterocyclic aromatics. Unhindered bases such as pyridines unsubstituted on positions 2 and 6 added to the unsaturations of the carbene backbone leading to a dinuclear allyl palladium complex, whereas 2,6-lutidine reacted with the metal centre to yield a mononuclear carbene complex. Reactions with methylim-idazole were found to give the mononuclear complex when up to two equivalents of imidazole were reacted, but addition on the carbene backbone was observed with 2.5 equivalents. [Pg.184]

Fischer-type metal-carbene complexes reaction of a carbanion on a metal carbonyl the anions obtained can be protonated or alkylated on the oxygen atom. [Pg.223]
