In(OTf)(3) is reported as the first catalyst having the ability to selectively catalyse both Markovnikov and anti-Markovnikov hydrothiolation of terminal alkynes under identical reaction conditions depending upon the nature of the thiol employed.

A general and efficient procedure for C-H alkenylation of arenes with a broad substrate scope catalyzed by Cp*Co was demonstrated with alkynes. A highly selective mono-alkenylation and sequential bis-C-H bond functionalization was displayed to exemplify the versatility of the cobalt catalyst. Isolation of cationic Cp*Co -alkenyl intermediate was achieved under identical catalytic conditions to further establish the proposed pathway.

An efficient Nickel‐catalyzed C−H bond alkoxylation of benzamides and olefinic carboxamides with alcohols were achieved for the first time using bidentate auxiliary. We demonstrated high‐functional group compatibility and tolerates wide‐range of alcohols.

An efficient catalyst-free, one-pot multicomponent reaction has been developed for the synthesis of pyrimidine functionalized pyrrolo-annelated derivatives. The method offers easy and column free separation, mild reaction conditions and high yields.

A copper catalyzed one-pot, three component reaction between barbituric acid, aldehydes and terminal alkynes has been developed for the construction of pyrano[2,3-d]pyrimidines via a tandem conjugative alkynylation/6-endo cyclization pattern. Screening of barbituric acid derived organic acceptors in conjugative alkynylation reaction and the synthetic applicability of conjugative addition products under one-pot conditions were documented for the first time.

A novel method for the construction of β,β-disubstituted indanones has been developed via tandem Nakamura addition-hydroarylation-decarboxylation process. Indium(III) triflate was demonstrated as a versatile multitasking catalyst, which catalyzes three different chemical transformations under one-pot conditions.

The first example of metal catalysed hydrothiolation of bromoalkynes has been demonstrated. Indium(III) trifluoromethanesulfonate was reported as the first catalyst which can catalyse the addition of thiols to bromoalkynes with absolute selectivity to generate (Z)-b-bromo vinyl sulfides in good yields.
