Ambient reaction conditions, excellent yields, and total avoidance of conventional isolation as well as purification are the noteworthy merits of this developed protocol.1 aKupwade, Ravindra, V.1 aKhot, Supriya1 aKulkarni, M., A.1 aDesai, Uday, V.1 aWadgaonkar, Prakash, P.  uhttps://library.ncl.res.in/content/diethylamine-dess-martin-periodinane-efficient-catalyst-oxidant-combination-sequential-one
