The IUPAC name of a carboxylic acid is derived from that of the longest carbon chain that contains the carboxyl group by dropping the final -e from the name of the parent alkane and adding the suffix -oic followed by the word “acid.” The chain is numbered beginning with the carbon of...
CONCLUSIONS We investigated isopropyl and tert-butyl propargyl carbonates 1b and 1c for the Pd(0)-catalyzed polycondensation with bisphenols and found that propargyl carbonates having a bulky alkyl ester group could lead to the formation of polyethers 3 with high molecular weight. The Mn values ...

Esters are also formed from alcohols and such inorganic acids as sulfuric, phosphoric, and nitric acids. Nitrate esters (e.g., glyceryl trinitrate, or nitroglycerin) are explosive. Phosphate esters are biologically important (nucleic acidsbelong to this group) and are used widely in industry as ...
As counter variables I assign reg[7:0] r_cnt... but after 3 variables all other reg[] suddenly becomes combinational groups instead of registered like it was before so that u_cnt,b_cnt,l_cnt are regestered group and b_bit become combinational group and all variables that I...
