摘要：

When trialkylaluminum reagents 2 bearing sterically demanding substituents are allowed to react with phosphaalkynes 1 a highly selective phosphaalkyne cyclotrimerization with incorporation of one organometal unit occurs (--> 5a-d). The resulting triphosphaalatricycloheptenes 5 are able to function as ligands in transition metal complexes (--> 6a,b), as illustrated by the reactions of 5a with nonacarbonyldiiron or the pentacarbonyltungsten tetrahydrofuran complex. When triethylgallium (7) is allowed to react with phosphaalkynes 1, tricyclic phosphorus-carbon-gallium compounds are generated (--> 8a,b).
