Colorants are disclosed that exhibit high color strength, bright shades, and high thermal stability. Such compounds have found application as colorants for polyethylene terephthalate (“PET”). Potential end uses include disperse dyes, non-warping pigments, decolorizable colorants, and the like. Compounds and methods for synthesis include benzodifuranone related compounds, benzene centered lactones, benzene centered lactams; benzene-centered thiolactones; naphthalene-centered lactones; naphthalene-centered lactams; naphthalene-centered thiolactones; anthraquinone-centered lactones; anthraquinone-centered lactams; anthraquinone-centered thiolactones; anthracene-centered lactones; anthracene-centered lactams; anthracene-centered thiolactones; hetero-aromatic-centered lactones; hetero-aromatic centered lactams and hetero-aromatic centered thiolactone compounds, and the like. Furthermore, resins such as PET or other polymeric resins containing the compounds are disclosed.

Cyclization/hydrosilylation of substituted 1-vinyl-1-(3-butenyl)cycloalkane's catalyzed by a 1:1 mixture of (phen)Pd(Me)Cl (1) and NaBAr4 [phen = 1,10-phenanthroline; Ar = 3,5-C6H3(CF3)2] formed silylated spirocycles in high·yield with excellent regio and diastereoselectivity. Cyclization/ hydrosilylation of substituted 3-(3-butenyl)eyeloalkenes or 2,3-diallyl-5,6-dimethyl-1,4-hydroquinone diacetate (16) formed silylated fused bicyclic complexes in good yield. Reaction of substituted 1,6,11-nonatrienes with silane catalyzed by 1/NaBAr4 led to cascade cyclization with hydrosilylation. This latter procedure was employed in the synthesis of silylated bicyclopentanes and a linear triquinane.
