2-alkenoic acid 1-alkyne

The nickel-catalyzed electrochemical carboxylation of l-(perfluoroalkyl) aUcenes proceeds regioselectively to afford 4-fluoro-4-perfluoroalkyl-3-alkenoic acids via a Ni(II)-allyl complex and a final F elimination (Fig. 19) [107]. Electrochemical carboxylation of alkynes in the presence of... 

Analog of HTIB. Various derivatives of HTIB with substituents in the iodoarene nucleus, ArI(OH)OTs, and three arenesnlfonyloxy analogs have been reported. [Hydroxy (mesyloxy)Iodo] benzene, PhI(0H)03SMe, and [hydroxy((+)-10-camphorsulfonyloxy)iodo]benzene are also known. [Hydroxy ((bis (pheny loxy) phosphoryl) oxy) iodobenzene], PhI(0H)0P(0)(0Ph)2, shows considerable potential for phosphate ester synthesis. Thus far, the a-oxyphosphorylation of ketones and -dicarbonyl compounds, the oxyphosphoryllac-tonization of alkenoic acids, and the conversion of terminal alkynes to monoketol phosphates with HPIB have been reported.
