Functionalizable alkylidenes: Tungsten complexes of phosphanyl-, amino-, alkynyl-, and tinalkylidenes and their dimetallic derivatization

The introduction of a heteroatom at the alkylidene carbon atom of calixarene complexes such as 1 results in an organometallic compound that shows properties of both Fischer carbenes and Schrock alkylidenes. Such modified alkylidenes allow access to dimetallic alkylidene complexes. For example, 1 reacts with [CuCOCl] to provide 2.
