A relationship is found between spectral-luminescent and photochemical properties for mono- and disubstituted chalcone derivatives (RCO)-C-1-CH=CHR2 [R-1, R-2 = Ph, 4-FC6H4, 4-BrC6H4, 2-furyl, 2-thienyl, 4-(PhCONH)C6H4, 4-NH2C6H4, 4-Me2NC6H4].

Siloxyallenes proved to be a usefulfunctionalintermediate in the preparation of (Z)-β-branched Morita–Baylis–Hillman type adducts by the reaction of aldehydes with silylacetylenes or siloxypropynes. Various (Z)-chalcones were stereoselectively synthesized from siloxypropynes via siloxyallenes.
