Rudler, H. published the artcileTungsten(0) alkylidene complexes stabilized as pyridinium ylides: new aspects of their synthesis and reactivity, Recommanded Product: (2-Bromoethyl)cyclopentane, the publication is Journal of Organometallic Chemistry (2001), 571-587, database is CAplus.
The interaction of dihydropyridines with alkoxycarbene complexes of tungsten has been shown to lead to pyridinium ylide complexes: this transformation has now been applied to the synthesis of a hydroxyl-containing ylide complex by ring-opening of the pentacarbonyl (2-oxacyclopentylidene)tungsten(0) complex and to the synthesis of a series of chiral ylide complexes both from chiral and non-chiral carbene complexes by the use of dihydropyridines and dihydronicotines, resp. The transfer of the alkylidene moiety of these complexes to nucleophilic olefins will be outlined and discussed. Especially relevant is the interaction of these pyridinium ylide complexes with unsaturated substrates such as dihydropyridines, enamines, and β-alkoxy bis(trimethylsilyl) ketene acetals. This latter reaction leads to conjugated carboxylic acids, and has been be applied to a new synthesis of a honey bee pheromone, the queen substance.
