The easily accessible haloalkynes can be converted to (Z)-2-halo-1-iodoalkenes in high yields with excellent regio- and stereoselectivity. The method shows good functional group compatibility. The resulting products could find broad applications.

A variety of arylboronic esters were efficiently carboxylated with CO(2) using a simple AgOAc/PPh(3) catalyst, affording the corresponding carboxylic acids in good yield. This simple and efficient silver(i) catalytic system showed wide functional group compatibility.

A palladium-catalyzed anti-Markovnikov hydroalkylation of β,β-difluorinated homoallylic alcohols with alkylzinc reagents has been developed. This method affords a wide range of synthetically useful gem-difluorinated compounds with good functional group compatibility.

Herein we report Pd catalyzed Suzuki type cross coupling between aryl halides and silylboranes for the syntheses of aryl silanes. This reaction shows a general substrate scope, excellent compatibility with electrophilic functionalities and good yields.

different approaches have been presented for estimating river environmental flow which hydrological approach has a lot addressed because of its need to access to limited data and moderately rapid assessment. this approach incorporates various methods therefore comparison between results of different methods is essential. the objective of this study is to investigate and compare the consequences...

introduction: different oral lesions have clinical characteristics which in some cases are similar. therefore, in these cases histopathological examination for correct diagnosis is necessary. the aim of this study was to evaluate the compatibility rate of clinical and histopathological diagnosis of oral lesions in zahedan school of dentistry. methods: in this retrospective study, determination ...

Email is a core communication mechanism for society. Current email protocols, like SMTP and IMAP, do not provide fundamental security properties like confidentiality, integrity, and authenticity. Users can optionally employ public-key cryptography like PGP on top of email, but the steps for doing so are too complicated for the average user. This paper presents SecurityTransparent Email with Aut...
