SLINTEC to Engage in Commercial Research with DSI

Sri Lanka Institute of Nanotechnology (SLINTEC) and D. Samson Industries (DSI) have signed a research agreement with a view to adding value to the DSI footwear product range. SLINTEC is a public-private partnership between the Government of Sri Lanka and six private companies, namely MAS Holdings, Brandix, Dialog, Hayleys, Loadstar and Lankem. One of its key directives is to enhance competitiveness of the products of the local industries in the global market, using nanotechnology and advance technologies. DSI is the market leader in manufacturing, retailing and one of the leading exporters of footwear in Sri Lanka. It is also the first local shoe manufacturing plant to receive ISO 9001- 2008 quality certification. Also DSI SAMSON GROUP currently working with University of Moratuwa and University of Colombo for several Research and Development projects. In the Picture are Mr. Kasun Rajapaksha – Managing Director DSI exchanging Agreement with Mr. Harin de Silva Wijeyeratne – Chief Executive Officer of SLINTEC in the presence of SLINTEC Board member Nihal Vitarana and Science Team Leader Prof. K.M.

Abstract

3-Pyridylboronic acid was prepared in high yield and bulk quantity from 3-bromopyridine via a protocol of lithium−halogen exchange and “in situ quench”. This technique was further studied and evaluated on other aryl halides in the preparation of arylboronic acids.
