A method for synthesizing a chlorine or bacteriochlorine derivative having the following formula: ** Formula ** in which: ** Formula ** represents a single or double carbon-carbon bond; X1, X2, X3, X4, X5, X6, X7, X8 are each, halogens (F, Cl, Br) and hydrogen atoms independently selected, provided that simultaneously X2, X4, X6, and X8 or simultaneously X1, X3, X5 and X7 are halogens, or that all X are halogens; R1, R2, R3, R4, R5, R6, R7, R8 are independently selected from H, -OH and -SO2R, in which each R is independently selected from - Cl, -OH, -amino acid, -ORn, -NHRn and -NR2n -, where Rn is an alkyl with 1 to 12 carbon atoms; Y is a fluorine or hydrogen atom; including the following step: (i) The solid state reduction of the corresponding substituted porphyrin in derivative and chlorine or bacteriochlorine using hydrazides in the absence of solvents and optionally in the absence of bases; wherein the corresponding substituted porphyrin has the formula: ** Formula ** |
