Synthesis of new meso-tetraarylporphyrins bearing cardanol and further transformation of the unsaturated chains

This paper deals with the synthesis of a new hybrid meso-tetraarylporphyrin-cardanol with the cardanol bearing an unsaturated chain. Cardanol is a renewable, natural, widely available and relatively low-cost material obtained as a by-product of the cashew industry which provides cashew kernels for edible use. The unsaturation in the chain in the new hybrid meso-tetraaryiporphyrin-cardanol leads to chemical and physico-chemical properties which are different from the saturated derivatives. The unsaturation also allows preparation of the corresponding epoxy compounds as well as self-metathesis derivatives. Copyright (c) 2006 Society of Porphyrins & Phthalocyanines.
