In this manuscript the synthesis of two new guanidine hydroquinoline ligands and six new zinc complexes were described. The activity of these complexes in lactide polymerization under industrial conditions is evaluated. Further, the depolymerisation is tested. The experimental MALDI-ToF-MS data were deposited here whereas other spectroscopic data (NMR and IR spectra) are deposited in the chemotion repository.

Bruker ultrafleXtreme

Bruker ultrafleXtreme equipped with a 337 nm smart beam laser in the reflective mode. THF solutions of trans-2-[3-(4-tert-butylphenyl)-2-methyl-2-propenylidene]malononitrile (DCTB) (5 μL of a 20 mg/mL solution), sodium trifluoroacetate (0.1 μL of a 10 mg/mL solution), and analyte (5 μL of a 10 mg/mL) were mixed and a droplet thereof applied on the sample target. Protein 1 calibration standard is the name of the protein mixture used for calibration. For spectra 4000 laser shots with 24% laser power were collected. The laser repetition rate was 1000 Hz.
