Piperazine-1-carboxylic acid TERT-Butyl ester;PIBOC;N- (T-BOC)Piperazine;N-T-Butoxycarbonylpiperazine A mixture of aldehyde (10 mmol), ethyl acetoacetate (10 mmol), urea (15 mmol), and HBF4 (1 mmol, 40% w/w) was stirred at 45 °C for the appropriate time . After completion of the reaction as indicated by TLC, the reaction mixture was poured onto crushed ice. The solid product was filtered, washed with cold water and a mixture of EtOH:H2O (1:1). The solid was dried and recrystallised from hot ethanol to afford pure product Common compound names. Examples of molar mass computations: NaCl, Ca(OH)2, K4[Fe(CN)6], CuSO4*5H2O, water, nitric acid, potassium permanganate, ethanol, fructose The activity of HBF4 (aqueous solution) as a catalyst in propargylation reactions is presented. Diverse types of nucleophiles were employed in order to form new C-O, C-N and C-C bonds in technical acetone and in air. Good to excellent yields and good chemoselectivities were obtained using low acid loading (typically 1 mol-%) under simple reaction conditions. PMCID: PMC4676292 PMID: 26693210.

Classical named applications developed prior to 1940 include Many salts, including the common aryl diazonium chlorides, can undergo violent decomposition and even explosion upon isolation. Diazo compounds tend to decompose at low temperatures with enthalpies of decomposition of −160 to −180 kJ/mol. Indeed, there have been multiple recorded incidents involving the loss of life from. Alkanes. In the absence of a spark or a high-intensity light source, alkanes are generally inert to chemical reactions.
