“…It has been reported that cationic surfactants having multi-polar groups showed higher antimicrobial activities compared to the corresponding lineartype cationics because of the much higher charge density carried by multi-polar cationics [59,60]. Surfactant properties of green geminis are also established by enantio-and diastereo-selection [61][62][63]. The surfactant properties of enantiomeric or diastereoisomeric surfactants show similar trends, i.e., those containing the chiral center in the hydrophobic moiety have been found to have similar properties to those of the corresponding stereochemically mixed surfactants [64,65].…”

Cationic gemini surfactants are a special class of second-generation smart surfactants. Since Menger first named them, gemini surfactants have drawn a wide and immense attraction from scientists throughout the whole world. These dimeric surfactants possess two or more hydrophilic with two or more hydrophobic head groups, chemically bonded with a linker, called the spacer group. These kinds of surfactants are used mainly in homogeneous catalytic reactions, as well as for solubilisation, emulsification, and many more technical applications. They are used in industries for electro-decoating, stabilization of adhesive polymer latex, antifriction agents, mining, paper manufacturing, preparation of surfactants including softeners, cosmetics, and most importantly, recent advancement in drug designing, synthesis, and application in medicine. The aim of this paper is to bring attention to the high performance second generation interfactants, with a focus on their synthesis, structure, types, and greener industrial application with high possibility of future prospect.

“…Optically active carbonate-type cationics were prepared using the (R)-alcohol or (S)-alcohol. The optical resolution of 1-(N,N-dimethylamino)-2-propanol using D -tartaric or L -tartaric acid has been reported by Chan et al However, the yields of the optically active amino alcohols were relatively low at 7% [71]. Here, the optically active amino alcohol was prepared by the enantioselective transesterification of vinyl propionate and 1-(N,Ndimethylamino)-2-propanol using the lipase according to the method of Hull et al as shown in Figure 10 [72].…”

Additional information is available at the end of the chapter http://dx.doi.org/10.5772/56163 . Introduction . . What is green chemistry?Chemistry has a key role to play in maintaining and improving our quality of life, such as in medicine, materials and electronics. However, it has also caused damage to human health and the natural environment. To make chemistry compatible with human health and the environment, "nastas and Warner have proposed principles of green chemistry, which help to explain what it means in practice [ ]. The principles cover a wide range of concepts, such as the molecular design and synthetic routes of product and the best means of waste disposal. In recent years, the establishment of a new field of green chemistry has been recognized as a necessary goal for sustainable development. The greening of chemistry will be realized by the discovery and development of new synthetic routes using renewable resources, reaction conditions and catalysts for improved selectivity and energy minimization, and the design of bio-/environmentally compatible chemicals. On the basis of these concepts, green polymer chemistry [ -], synthetic organic chemistry using environmentally friendly processes [ , ] and technology for the production of bio-based product [ ] have so far been developed and improved. . . Requirements for green surfactantsSurfactants are widely used in large quantities in industrial fields including fibers, pharmaceutical agents and foods, and are also used as household detergents. Owing to the watersolubility of surfactants, they are generally difficult to recover or reuse therefore, they are discharged as drainage into the environment if they are not biodegradable. On the other hand, surfactants should be chemically recycled, particularly after industrial use, in order to conserve
