Innkeeper
Inns are generally establishments or buildings where travelers can seek lodging, and usually, food and drink. Inns are typically located in the country or along a highway; before the advent of motorized transportation they also provided accommodation for horses. History Inns in Europe were possibly first established when the Romans built their system of Roman roads two millennia ago. Many inns in Europe are several centuries old. In addition to providing for the needs of travelers, inns traditionally acted as community gathering places. Historically, inns provided not only food and lodging, but stabling and fodder for the travelers' horses, as well. Famous London examples of inns include The George and The Tabard. However, there is no longer a formal distinction between an inn and several other kinds of establishments: many pubs use the name "inn", either because they are long established and may have been formerly coaching inns, or to summon up a particular kind of imag ...

Kabachnik–Fields Reaction
In organophosphorus chemistry, the Kabachnik–Fields reaction is a three-component organic reaction forming α-aminomethylphosphonates from an amine, a carbonyl compound, and a dialkyl phosphonate, (RO)2P(O)H (that are also called dialkylphosphites). Aminophosphonates are synthetic targets of some importance as phosphorus analogues of α-amino acids (a bioisostere). This multicomponent reaction was independently discovered by and Ellis K. Fields in 1952. The reaction is very similar to the two-component Pudovik reaction, which involves condensation of the phosphite and a preformed imine. : The first step in this reaction is the formation of an imine, followed by a hydrophosphonylation step where the phosphonate P-H bond across the C=N double bond. The starting carbonyl component is usually an aldehyde and sometimes a ketone. The reaction can be accelerated with a combination of dehydrating reagent and Lewis acid A Lewis acid (named for the American physical chemist Gi ...

Russian-language Surnames
Russian (russian: русский язык, russkij jazyk, link=no, ) is an East Slavic language mainly spoken in Russia. It is the native language of the Russians, and belongs to the Indo-European language family. It is one of four living East Slavic languages, and is also a part of the larger Balto-Slavic languages.
