their reactivity in [2+2+2] cycloaddition reactions compared with highly active [CpCo(H2CCHSiMe3)2] (1). Whereas 1 is an excellent precursor for the synthesis of [CpCo(olefin)(phosphite)] complexes (2 a–f), [CpCo(phosphite)2] complexes (3 a–e) were prepared photochemically from [CpCo(cod)]. The complexes were evaluated in the cyclotrimerization reaction of diynes with nitriles yielding pyridines. For

Aspects disclosed herein include fully or partially degradable polymers, liquid formulations comprising such polymers, methods for treating or managing a condition in a subject using such polymers, methods for using such polymers, and methods of synthesizing such polymers. Aspects disclosed herein also include monomers suitable for forming a partially or fully degradable polymer and methods for forming such monomers.
Decomposition mechanism of a cobalt-coordinated phosphite–olefin ligand under irradiation
center via P atom and olefin moiety upon irradiation, photolysis of the latter led to the subsequent formation of the phosphorus-free [CpCo(η4-1,3-butadiene)] complex (6). A mechanistic rational of the decomposition reaction based on an Arbuzov-like rearrangement is suggested.
