Der Einbau von Magnesium in Liganden der Chlorophyll‐Reihe mit (2,6‐Di‐ t ‐butyl‐4‐methylphenoxy)magnesiumjodid

of Magnesium into Ligands of the Chlorophyll Series by (2,6‐Di‐t‐butyl‐4‐methylphenoxy)magnesium Iodide Experimental details are given for the new method of introducing magnesium into porphinoid ligands by (2,6‐di‐ t ‐butyl‐4‐methylphenoxy)magnesium iodide (1) , previously published in preliminary form [1]. Besides magnesium octaethylporphyrinate (14) , methyl pyrochlorophyllide a (10) , methyl chlorophyllide a (8) , and methyl bacteriochlorophyllide a (12) , the complexation of pheophytin a (2) to chlorophyll a (3) and of pheophytin b (4) to chlorophyll b (5) are described.
