Synthesis of propargylic ethers via Lewis-acid mediated nucleophilic substitution of propargylic esters

Direct displacement of propargylic esters is reported 10 mol% of TiCl4 were used to carry out this novel, nucleophilic substitution.

TiCl4-mediated nucleophilic substitution of propargylic esters

Direct displacement reactions of propargylic esters are reported. 10 mol% of TiCl4 were used to carry out a nucleophilic substitution. Scope and limitation of this novel reaction are described. (C) 2000 Elsevier Science Ltd.

Photolyses of 1,4-Bis(1,1-diarylhept-2-ynyl)benzenes and 1,4-Bis(1,1-diarylalkyl)benzenes

Photolyses of 1,4-bis(1,1-diarylhept-2-ynyl)benzenes or 1,4-bis(1,1-diarylalkyl)benzenes 2 in a tetrahydrofuran-methanol mixture gave 1-biphenyl-4-yl-1,1-diarylhept-2-ynes or 1-biphenyl-4-yl-1,1-diarylalkanes 3 as major products and biaryls 1 as minor products.The products 3 were obtained with quantum yields of 0.010-0.020, respectively.

Photolysis of 1,1,1-Triarylalk-2-enes and 1,1,1-Triarylhept-2-ynes. A Novel Generation of Aryl(alk-1-enyl)carbenes ans Aryl(alk-1-ynyl)carbenes

Upon UV irradiation in methanol, 1,1,1-triarylhept-2-ynes underwent an α,α-elimination of two aryl groups to give a biaryl and the corresponding carbene which reacted with methanol to give a 1-aryl-1-methoxyhept-2-yne. 1,1,1-Triphenylalk-2-enes underwent α,α-elimination of two phenyl groups and also elimination of an alkene and a phenyl group to give biphenyl and a 1-phenylalkene respectively.In both cases, the corresponding carbenes were formed and were isolated as methanol insertion products (a 1-methoxy-1-phenylalk-2-ene and diphenylmethyl methyl ether, respectively).A rearrangement product, a 1,1,2-triphenylcyclopropane, was also formed.

Photolysis of 1,1,1-Triarylhept-2-ynes. Generation of Phenyl(hex-1-ynyl)carbene

Photolysis of 1,1,1-triarylhept-2-yne in methanol gave biaryl and 1-aryl-1-methoxyhept-2-yne, which may be derived from the insertion of aryl(hex-1-ynyl)carbene into the OH bond of methanol.The carbene may be generated by photo-α,α-elimination of two aryl groups from the substrate.
