The beginning of 1970’s may well be regarded as turning point in the area of organic synthesis when an efficient and straight forward strategy for the reaction of primary and/or secondary alcohols with variety of nucleophiles in the presence of triphenylphosphine and azodicarboxylate reagent was discovered by O. Mitsunobu and since then rapid progress has been made in understanding and applying the Mitsunobu reaction for various derivatization reactions. Due to versatile applications and mild reaction conditions associated with the said strategy, the Mitsunobu reaction has received much attention in the last almost fifty years and has been well reported. The basic objective of this review is to pay attention on the recent advances and applications of the Mitsunobu reaction particularly in last decade. The attention has also been paid to describe various modifications which have been explored in the traditional Mitsunobu reaction by substituting P (III) reagents or azodicarboxylate reagents with other suitable reagents or else using an organocatalyst with the objective to improve upon the traditional Mitsunobu reaction. In the present review we wish to report the major advancements achieved in last few years which are likely to be beneficial for the researchers across the globe.

Recent Advances

With the rapid progress of the use of miniature sized antennas, wireless communication technology has quickly risen. Not only have the size of the antenna but also its cost, efficiency and ease of assembly all been taken into account during the antenna design. Conformal antennas are suggested to satisfy all these requirements. Conformal antennas have broad commercial, defense and several civil services applications. In aircraft and boats it is the most important and necessary time. Patch antennas are often regarded the best choice for such conformal antennas. In this paper, we address the conformal transmitters with different substrates used for antenna design. With this article, we create a modeling of conformal antennas with latest developments by examining early events

Major Progress

The use CCD detectors has allowed a major progress in abundance derivations for globular cluster stars in the last years. Abundances deduced from high dispersion spectra now correlates well with other abundance indicators. I discuss some problems concerning the derivation of accurate metal abundances for globular clusters using high dispersion spectra from both the old photographic and the most recent CCD data. The discrepant low abundances found by Cohen (1980), from photographic material for M71 giants, are found to be due to the use of too high microturbulences.
