Abstract
Oligoetherketones of the structure 2a,b can be generated by repetitive insertion reactions of terminal biscarbenoids 4a,b into the O-H bends of diols like 5. The formation of the corresponding ring systems 7a a nd the involved carbene dimerization leading to 8b are processes which compete with the linear polyinsertion. A related one-component reacti on can be performed with omega-hydroxy-1-diazo-2-alkanones (13a-c --> 14a-c).
