The Chemistry of Guanidine, Guanidinium, and Guanidinate Compounds [PDF]
Australian Journal of Chemistry, 2014 Guanidine-based functional groups occur in many branches of chemistry, due in part to their ability to exist as neutral (guanidine), cationic (guanidinium), and anionic (guanidinate) entities. With such a rich chemistry, it is undoubtedly difficult for researchers to follow the development of so many aspects of guanidine chemistry, especially when ...
