- Tin-free reductive photochemical carboxymethylation of olefins with α- alkylthioacetates
-
An efficient tin-free reductive photochemical carboxymethylation of olefins with α-alkylthioacetates is developed, which (a) is an experimentally simple technique furnishing substituted derivatives of fatty acids in moderate to good yields, (b) is compatible with polar/protic functional groups and solvents, (c) does not require a special reducing reagent, (d) is fairly insensitive to the presence of dissolved oxygen and, generally, does not require degassing prior to irradiation. The critical feature of the mechanism is the 'reluctance' of short-lived MeS' to group- transfer, resulting in hydrogen abstraction from the media.

- Dibicyclo[3.1.1] and [2.2.1] heptyl and dibicyclo [3.1.1] and [2.2.1] heptenyl polyamines having a piperidine moiety
-
Novel dibicyclo [3.1.1] and [2.2.1] heptyl and dibicyclo [3.1.1] and [2.2.1] heptenylalkyl polyamines are useful antimicrobial agents, as well as algae inhibitors. They are especially useful as hard surface disinfectants and as additives to oil well drilling muds, injection brines and industrial water where bacterial control is desired.

- Di-bicyclo[3.1.1] and [2.2.1]heptyl and di-bicyclo[3.1.1] and [2.2.1]heptenyl ketones
-
Novel di-bicyclo[3.1.1] and [2.2.1]heptyl and dibicyclo[3.1.1] and [2.2.1]heptenyl ketones are useful as intermediates for preparing novel polyamines useful as antimicrobial agents, as well as algae inhibitors.
