FeTPPCl/FeCl3Co-Catalyzed One-Pot Green Synthesis of α-Diaryl-β-alkynol Derivatives via Propargylic Carbocation Chemistry

A green and highly efficient one-pot method for α-diaryl-β-alkynol derivatives in water at room temperature was developed using the cocatalysis of a Lewis acid and meso-tetraphenylporphyrin iron(III) chloride (FeTPPCl). The unprecedented transformation was promoted by a modulation of the charge properties of propargylic carbocation chemistry and the use of an in situ-generated oxonium ylide as a matching nucleophile. The reaction was performed in water at room temperature with a highly step-economic manipulation in good to excellent yields and with a broad substrate scope. Water also acts as the third reactant for the one-pot transformation. Notably, the FeTPPCl catalyst can be directly reused four times with a slight discount in yields.

Aryl carbinols as nerve agent probes. Influence of the conjugation on the sensing properties

Two new aryl carbinols (1 and 3) have been synthesised and characterised and their ability as OFF-ON probes for the chromogenic detection of the nerve agent simulant in acetonitrile has been tested. In addition compound 2 has been also studied. The carbin

The influence of a 1,1-diarylvinyl moiety on the photochromism of naphthopyrans

1,1,3-Triarylpent-4-en-1-yn-3-ols, efficiently obtained in two steps from 1,1,3-triarylprop-2-yn-1-ols by a Meyer-Schuster rearrangement and subsequent addition of lithium trimethylsilylacetylide, react with either a 1- or 2- naphthol to afford photochrom

Tertiary acetylenic alcohols and peroxides derived from 4,4′-bis(dimethylamino)benzophenone (michler's ketone)

Tertiary acetylenic alcohols were obtained by treatment of 4,4′-bis(dimethylamino)benzophenone with 1-alkynyl- and 2-phenylehynyl, as well as lithium tert-alkylperoxyacetylides.

Tertiary acetylenic alcohols and diols on the basis of phenylacetylene and 2-methyl-3-butyn-2-ol

A procedure has been proposed for the synthesis of tertiary acetylenic alcohols and diols by treatment of phenylacetylene or 2-methyl-3-butyn-2-ol with butyllithium and subsequent reaction of lithium phenylacetylide or lithium 4-lithio-2-methyl-3-butyn-2-

Synthesis, Absorption Spectra, and Photostability of Triarylmethane Dye Ethynylogues Containing Trifluoromethyl Group(s)

Triarylmethane dye ethynylogues 7'-11' containing trifluoromethyl group(s) are synthesized in moderate to good yields by treating 1,1,3-triaryl-2-propyn-1-ols, prepared from diaryl ketones and lithium arylacetylides bearing trifluoromethyl group(s), with
